SystemRescueCD quits Gentoo moves to ArchLinux

Thanks @Sabayonino for forking it off and giving us the LRS. I'll grab the torrent and try to seed it for as long as I can.

Also, thank you @NeddySeagoon for hosting it !

edit1: I think we also should have a wiki entry or some other way to inform others of the LRS. New users may not be aware of this thread.

As project LRS seems backuped by many (also admin and mod) and we all miss Gentoo driven systemrescuecd.
Do you think that it would be possible to host it officially in the download section of the Gentoo website ?

That would be great and easier !

Would also help people googling for it ;-)

Best,

Tony0945,

It won't happen because hosting LRS inside Gentoo namespace implies Gentoo endorsement and possibly Gentoo security updates.
Neither of those will happen.

What gentoo developers do on their own servers is up to them.

Perhaps Sabayonino can post it on github or Sourceforge.net?

EDIT:
I did download some note pages from system-rescue-cd.org but haven't done anything with them yet.
it seems a daunting task. Ultimately an ebuild would be good. In an overlay of course.

Thank you for making this possible, Sabayonino

I am trying to make this iso directly bootable from grub2, but I need some help. Maybe someone of you sees my error(s).

I downloaded the iso file and placed it on a partition created as /dev/sda4 (formated with ext4) which is mounted at /lrs.

I then modified /etc/grub.d/40_conf to the following:

I edit my /boot/grub/grub.cfg by hand.
If it is of any help, here is my grub.cfg entry for LiveRecoverySystem CD.

It works now, after I had to do little additions/corrections like adding the two insmode lines and set root=
I also removed /lrs in set isofile. Thanks proteusx

Hey, thanks for keeping Gentoo SystemRescueCD going as LiveRecoverySystem! It's great for partitioning and formatting disks (unless you're creating encrypted disks and need rngd, for that I use a Kubuntu install disc) and putting smiles on the faces of Mom's friends who thought for sure they lost pictures of their grandkids forever

Not happy that it still has to be larger than a CD-ROM, but no big deal, times have changed.

I have the torrent for LRS-201908-13, along with the Linuxtracker.org torrent of SRCD v5.3.2, running on a VPS.
Announce new versions of LRS on this thread and I'll join in with the new torrent.

Thank you!

EDIT: Just a suggestion, one of the important packages that SystemRescueCD always lacked was rng-tools. If you want to create encrypted partitions, you need entropy provided via rngd, and for that reason I often used the Kubuntu install CD in addition to, or instead of, SRCD when initially setting up a disk for Linux. Now that we have LRS and it's no longer capped at 700 MB, you might want to add sys-apps/rng-tools, with rngd disabled at boot, so that people can create encrypted partitions using LRS.

redblade7,

You can convert all the virtual drive formats among themselves.
The physical media does not matter.

Hi guys !

As testing RAW image available on my dropbox (Shared link) . It works on my PC and others that I've tested. (mostly Intel Chipsets and some AMD Ryzen , thanks Xdarma for testing :roll:

)

*.img is a raw image you can put on USB/SDD/SATA harddrive using :
Rosa image builder
app-cdr/isoimagewriter
Or BalenaEtcher
Or simply decompress .zst file to device target (see LRS.info)

FSA (fsarchiver) and VDI (VirtualBox drive) files are also available , please configure the 3 partitions before using Fsarchiver as explained on LRS.info file.

It can boot from grub2 on hybrid BIOS+UEFI boot. (only UEFI if restored by FSA file archive)

Image can be updated and you'll have a pure Gentoo system on your USBstick/Hdd

Please keep in mind that performances can be different from USB chipsets and controller. But should be works fine with low I/O .

Memo for Nvidia+Intel Video cards : If the system won't boot try to disable ACPI and choose VESA video driver.

Root has a XFS filesystem 'cause it can grow the filesystem on a running and mounted partition. RAW image has 7.7Gb data size (~4.4 GB files size). It can be put on >=8GB drive and it can use all the free space .

Just for fun !

Happy new 2020 !

USB Performance
PS : I've tested *.img file on different USB devices.

Lexar Media, Inc. JumpDrive Tough S75 3.0 128GB : Works but very low performance on write
Lexar Media, Inc. JumpDrive Tough ?? Model 3.0 32GB : Works fine with few write operations . High I/O go to freeze :lol:

Kingston Technology DataTraveler 100 G3/G4/SE9 G2 : Freeze at boot :evil:

SanDisk Corp. Ultra ??? 2.0 : works but very slow
SanDisk SD8SNAT1 (SSD 256GB) via USB adapter : Works fine.
SanDisk SD8SNAT1 (SSD 256GB on SATA controller) : Works fine

Other USB 2.0 devices : Works with very slow performances
Other USB 3.0 devices : Some USB works with low I/O , others are very slow with partial freeze.

PPS : No more free space on my dropbox to keep old ISOs .. I'm looking for other free cloud/share solutions , I'm trying to boot LRS on ISO9960 running Isolinux and keep all the tools that i've installed (DVD will be needed).

I have a question, but did not want to mess this thread with support, so asked in a separate thread. Maybe someone sees my probably obvious error? :twisted:

I have two questions, while updating I got ccache error indicating portage could not create temporary file. Is this a known issue? Then I have no sound, with hd-audio. I thought I should report, as its a quite common device. For now, I have removed ccache from features to do an initial world update, and I'll look into the sound issue once system is up to date. A general question as I don't quite understand usermanagement on these livesystems; where can I configure a login with restricted user with mandatory password for login? I am asking, as an usb stick can be forgot or lost. And the normal setup seems to be that there is an autologin, with an account without password, where I can change to root by just typing su and hitting enter without password. How can this be changed towards a behaviour of a normal setup? I tried to passwd from within root, but that does not seem to persist. I also tried to create a user, but that doesn't seem usefull when a reboot & a startx followed by su gets me admin rights. On the other side, when I install something, or change some settings, those seem to persist, so it is aparently not a read only system. I would be grateful if someone could enlighten me. Thanks a lot for your great work.

Is there any way for us to share in the build process?

sabayonino · Veteran Joined: 03 Jan 2012 Posts: 1014

There isn't any repository (like GIT,CVS ...) .
No code to share.

SImply I play in chroot environment on a loop device of a RAW image and I build the system just like gentoo chroot installation.

See LRS.info file

I'm just trying to update the last Gentoo based Sysrescuecd per the instructions on the CD. Besides the copy not working (error messages), I found that only the 32 bit apps were copied. Am I correct that sysrescuecd boots either a 32 bit or 64 bit kernel, but even if booting a 64-bit kernel, all the applications are 32-bit?

Trying to feel my way through the process.

I found it neccesary to turn off pam (as I have on all of my machines). Why would a rescue CD have multiple seats?
