Thanks for this 11.2 LiveDVD, released on my birthday! What a birthday present, gnome 3 here I come.
-----

Question: Is there an official guideline for installing a stage4/livedvd?

I'd like to install the entire LiveDVD onto my base system....
....is it really as easy as just copying all the files?

The LiveDVD may have gcc 4.5, but if you were to go install gentoo with it, you'd be back to stable, gcc-4.4, two version behind.

My computer will probably be dead of old age before Gentoo catches up unmasking gcc 4.6, as 4.5 isn't even marked stable yet.

When I first discovered Gentoo (almost 10 years ago),
I switched to it because it was bleeding edge and built for my system, yet stable too.
An Intel i7 needs gcc 4.6 for full advantage of cpu, and improved multi-threading in >=gcc-4.6
-----

FYI: I've successful emerge -e system, with gcc 4.6 on an Intel i7 950, with -02 "-fenable-multi-threading". I see no reason why 4.6 is hard masked.

Request to Developers: Bring back stage1 install, so us users can run gcc 4.6 without having remerge packages 2 & 3 times.

-----------------------

:?: Actually, I plan on building weekly GCC 4.6 Stage1/2/&3, and gentoo-current/stage1 files
(I figure this may help the gcc 4.5/4.6 unmasking stable)
-- To be posted soon if anyone is interested, unless already available, either, let me know & PM Me.

EDIT: What my custom hybrid stage1,2,&3s will feature (not included in gentoo-current/stage3)
-=<stage1/stage3 for corei7>=-
# SSD optional optimization script :!:
-- Native TRIM Support (XFS, Ext4, & ~Btrfs)
-- No Swap/Swapfile
-- RAMDisk (virtual disk in memory) partition for /tmp & /work for portage
(writes from compiling would kill an SSD otherwise)
# GCC 4.6.1 (native corei7 + new multi-threading optimizations)
-- glibc,binutils,libtool,etc, for GCC version
# configure /etc & portage for new features (emerge --sync / -DNu won't downgrade)
# corei7 optimized bootstrap.sh, make.conf
# Linux Kernel >=2.6.39

Then weekly snapshots of gentoo-current (stable) stage1 files for standard install.

Again, let me know if this has already been done, otherwise, is there interest for this?

Either way, Let me know, PM Me.

PostPosted: Mon Aug 08, 2011 12:20 pm    Post subject: I was able to install the LiveDVD 11.2 to harddisk Reply with quote

Hi, i am writing from the LiveDVD 11.2 installed to HDD.

Here is how to:

Reused old how to from here with little modifications.

http://www.gentoo-wiki.info/HOWTO_Lightning_fast_install_from_LiveCD

And i have also created the wiki
Install_LiveDVD_11.2_to_hard_disk_drive
http://en.gentoo-wiki.com/wiki/Install_LiveDVD_11.2_to_hard_disk_drive

Steps:
1#boot into the LiveDVD and create your filesystems
open terminal and sudo su -
Code:
fdisk /dev/sda
##and partition your HDD the way u like, format and mount to (/mnt/gentoo and /mnt/gentoo/boot)etc

2# copy the DVD (around 8.5GB)
Code:

eval `grep '^ROOT_' /usr/share/genkernel/defaults/initrd.defaults`
cd /
cp -avx $ROOT_LINKS /mnt/gentoo
cp -avx $ROOT_TREES /mnt/gentoo
cp /etc/passwd /etc/group /mnt/gentoo/etc


3# finish the system and chroot into it.
Code:

mkdir /mnt/gentoo/proc /mnt/gentoo/dev
cd /mnt/gentoo/dev
mknod -m 660 console c 5 1
mknod -m 660 null c 1 3
mount -t proc none /mnt/gentoo/proc
mount -o bind /dev /mnt/gentoo/dev
mkdir /mnt/gentoo/sys
chroot /mnt/gentoo /bin/bash
env-update
source /etc/profile
export PS1="(chroot) $PS1"


4# Configure FSTAB

Configure /etc/fstab
Code:
nano -w /etc/fstab


Code:

/dev/sda1   /boot        ext2    defaults,noatime     1 2
/dev/sda2   none         swap    sw                   0 0
/dev/sda3   /            ext3    noatime              0 1

/dev/cdrom  /mnt/cdrom   auto    noauto,user          0 0

proc        /proc        proc    defaults             0 0
shm         /dev/shm     tmpfs   nodev,nosuid,noexec  0 0


5# Mount the LiveDVD and copy kernel image and initramfs
Code:

mkdir -p /mnt/cdrom
mount /dev/cdrom /mnt/cdrom/
cp /mnt/cdrom/boot/gentoo /boot/kernel
cp /mnt/cdrom/boot/gentoo.igz /boot/initramfs


6# configure and install GRUB

Code:

# nano -w  /boot/grub/grub.conf


Code:

default 0
timeout 30
#splashimage=(hd0,0)/boot/grub/splash.xpm.gz

title Gentoo Linux         
root (hd0,0)
kernel /boot/kernel real_root=/dev/sda3
initrd /boot/initramfs


Code:

grub
grub> root (hd0,0)
grub> setup (hd0)
grub> quit



You can reboot after this and the system will start from HDD and autologin with guest account to the KDE environment.
There might be some details that need some ironing.
This is just quick take on this while listening on a long conf call

enjoy.

Hmm... I started GNOME (in a kvm, I guess I'm in fallback mode), and when I click on any of the folders in the Places menu, it starts qmmp 8O

I edited the wiki since the last released livedvd-x86-amd64-32ul-11.2.iso contains gentoo kernel instead of gentoo-r1. I edited it for x86, usually a fork step may be done to install a x64 kernel.

This looks great, just have to try it out first.

However I have some questions. I also worry, just as awalp, about what will happen if one does an emerge -avuDNt world on the live dvd, alot of complaints on the masks? Or is the package.keywords/.mask/.unmask etc designed to have as little conflicts as possible?

I also wonder, since I would like to use this liveDVD as a liveUSB, and then it would be nice if one could update to the next release of the liveDVD. Will there be support for this, and if so, will I then get a new set of package.keywords/.mask/.unmask files and just run an update?

PostPosted: Thu Aug 11, 2011 8:32 am    Post subject: No root access Reply with quote

How do I get root access on the live DVD? When I go to a terminal window and type "su -" I get a password prompt. Leaving it blank gets me an authentication failure. Typing "passwd" in a terminal window gives me a prompt asking for the current root password. What is the current root password? The live DVD is totally useless without root access. I can't even partition my hard disk to install Gentoo Linux. The minimal install Gentoo CD doesn't make me enter a root password. It just logs me in as root from the beginning. Unfortunately, the minimal CD doesn't support my wireless network adapter like the live DVD does. HELP?

The text on the website says
Quote:
# Special Features:

* Writable filesystems using AUFS so you can emerge new packages!
* Persistancy for $HOME is available; press F9 for more info!



So I pressed F9, but nothing happend. I tried Firefox 3.6.17 and Konqueror 4.7.0. What browser supports this "F9 for more info"? :wink: :wink:

Seriously:
Thanks! :D I was glad to see that there is a new Live DVD, since I bought myself a AMD Fusion system and need a Live DVD using the latest kernel and Radeon drivers. I will check it out this evening.

The F9 business is probably during the kernel loading or init stage of the livedvd. Just a guess.

PostPosted: Thu Aug 11, 2011 1:38 pm    Post subject: press F9 on the first screen you see after booting the DVD Reply with quote

Otherwise read the text from the DVD directly


Gentoo-11 ~ # cat /mnt/cdrom/isolinux/F9.msg
Special Features:

AUFS Options:

aufs_mem=X
Allocate memory for the AUFS writable branch. Default 420M
Example: gentoo aufs_mem=2G (recommended for 3D desktop use)

Boot with persistence mode:

You have two ways to use persistancy for $HOME
1) After you have dd the Gentoo liveUSB image to your device, use fdisk to create
a secondary partition, then format this partition and include a blank file called
"persistence-mode".
2) Same as above but filename can reside on a separate device. First method is
the recommended way.

Persistance mode requires atleast 42M of space. You can increase the size of the
filesystem image created by the script with "persistence_mb=xxx"

Example: gentoo persistence persistence_mb=100

Helllo,

I have a few problems with installing the livdvd to my hard disk.

When I have to mount the cdrom I see this message :
mount: /dev/sr0 already mounted or /mnt/cdrom busy
mount: according to mtab, /dev/sr0 is mounted on /newroot/mnt/cdrom
mount: /dev/sr0 already mounted or /mnt/cdrom busy
mount: according to mtab, /dev/sr0 is mounted on /newroot/mnt/cdrom

and the following step (cp /mnt/cdrom/boot/gentoo /boot/kernel) gives this message :

cp: cannot stat `/mnt/cdrom/boot/gentoo': No such file or directory

How to solve this ?

Installing the LiveDVD to HD was actually much simpler this way...

from an existing working gentoo install, install to a new partition

(create a new partition for the livedvd install)
Code:

fdisk /dev/sda
(reboot)
mkfs.xfs /dev/sda8
mkdir /mnt/livedvd_hd
mount /dev/sda8 /mnt/livedvd_hd

mount newly made partition

mount livedvd, then mount actual livedvd squashfs root /
Code:

mount /dev/cdrom

mkdir /mnt/livedvd
mount /mnt/cdrom/image.squashfs /mnt/livedvd

cd /mnt/livedvd
cp -a * /mnt/livedvd_hd 

copy livedvd root / to new hd install

delete fake /dev
create /dev empty directory
Code:

rm -rf /mnt/livedvd_hd/dev
mkdir /mnt/livedvd_hd/dev
cp /etc/fstab /mnt/livedvd_hd/etc/fstab
cp /etc/resolv.conf /mnt/livedvd_hd/etc/resolv.conf

copy your fstab, correct it for new partition,
#/boot so you don't overwrite your boot
copy resolv.con

(if not mounted, mount /boot)
Code:

mount /boot
cp /mnt/cdrom/boot/gentoo /boot/gentoo
cp /mnt/cdrom/boot/gentoo.itz /boot/initramfs 
nano /boot/grub/menu.lst 

reboot
copy kernel to exisiting /boot
copy livedvd initramfs to exisiting /boot
add new entry line for new livedvd_hd gentoo partition and newly copied kernel


Then you end up with a gentoo install, that has tons of mismatched compiled files and missing linkages, I noticed most of the LiveDVD was compiled with gcc 4.6.1, while only gcc 4.5.2 is installed, making random emerges fail.
-- Though this only happened when I was chrooted, it worked fine when booted. weird.

Is there any way to access DVD filesystem (contents) inside LiveDVD environment?
mount says that /dev/sr0 is mounted on /newroot/mnt/cdrom, but there is empty directory.

Also converting image to USB stick (to have collection of pre-downloaded stages/snapshots/distfiles in one place) did not help.
mount shows /dev/sdb1 mounted on /newroot/mnt/cdrom also empty.

You don't need to mount the livedvd since it's already mounted once you are booted into it. If you want to use the packages on the livedvd to rapidly install Gentoo, then you should follow this guide http://tinyurl.com/65kz47g

The Image doesn't need to be converted for USB booting as it's already a hybrid image which can either be burned to DVD or DD/CAT to a removable device i.e usb stick or hdd

I understand this, and successfully using Live on DVD and on USB. My problem is that I have no access to liveDVD contents. And if I want to include recent stage in the DVD root - I could not access it!
The only right way seems to go - with USB drive splited in two partitions, with DVD converted (not dd, as this will not work) onto the first and stage/snapshot/distfiles going onto second.

Update: or make use of persistence mode, which seems to be the only supported way to have own files on media

Update2: and persistence mode is not working as expected :) I managed to use partition for my files storage, and access them from within liveDVD but persistence itself is broken (https://bugs.gentoo.org/show_bug.cgi?id=379265)

persistence mode is only for $HOME folder not / and that bug is fixed and will be available in the maintenance release coming up soon.

Hi,

While I found out that "da" was missing fron the LINGUAS environment variable in /etc/make.conf, I decided to remake the liveDVD.

No problems mounting the DVD, and the image.squashfs filesytem, copying the files from here, set up a chrooted environment for re-emerging with the updated LINGUAS.
I also managed to make a new version of image.squashfs, and got made a new iso image, which I can loop mount without any problems, and also loop mount the inlined image.squashfs filesytem, but when I try to boot the it does not work.

I also tried to look at http://en.gentoo-wiki.com/wiki/Build_Your_Own_LiveCD_or_LiveDVD but in vain.

So can you tell me how you are building the iso image?

In advance thanks,

Lennart
