When can I reboot (during Install)

StevenC21 · n00b Joined: 07 Jun 2018 Posts: 63

Hey. So, basically, I REALLY need to reboot my VM. I am installing Gentoo in a VM, and earlier today my laptop was in a different physical location. Now, I'm back home, but the IP addresses have a load of issues, which basically means I'm shooting in the dark about the networking section. So I need to reboot the VM to fix it. I am at "Networking Information". If I reboot, what is going to happen? Will I lose everything?

[Moderator note: the "messed up IP addresses" are discussed in I messed up my Networking. Please Help.. -Hu]

is this a joke?

no rebooting will not erase your hard drive. you will have to mount the partitions and chroot from your bootable media again and then pick up where you left off.

Why would I make a joke. You don't need to be a jerk.

sorry it came off like that with "but the IP addresses have a load of issues,"

StevenC21 · n00b Joined: 07 Jun 2018 Posts: 63

Its ok. What I mean is that my IP information is definitely messed up. As in, the IP is 10.0.1.15 when it ideally would be 192.168.1.(something).

Just restart your ethernet service.

First off, really sorry for being a n00b. Second, which part of ifconfig will get my eth0/whatever names?

Also darn because I already set up the Networking using eth0. I'll have to go redo that.

To address your original question, you can reboot whenever you like. You will need to redo commands that change live state, such as the current directory, the current root directory, or networking configuration. You do not need to redo commands that would cause data loss, such as changing the partition table, creating LUKS volumes, or formatting filesystems.

Your problem does not require rebooting the VM. That might be the fastest approach for you, but it is not the only solution.

I made a change to my response on the other thread because now knowing this, it changes everything...

StevenC21,

No need to apologise for being new to Gentoo, or even to Linux.
We were all new at one time and most of us remember the learning curve.

You can reboot at any time during the install. The work you have done on /mnt/gentoo and inside the chroot will still be on your VM hard drive.
It just won't be attached at /mnt/gentoo and you won't be in the chroot is all.

Thank you for the kind words. In addition, would you mind looking at some of the other questions I have asked around the site? I'm afraid I might not get an answer.

StevenC21,

It looks like you are in good hands on the two posts you referenced.

Thanks for the help guys! However, I'm still a bit lost.

I don't know what the kernel command line is, nor do I know what net.setup is, and I don't believe I've ran it yet. I don't know what sysrescuecd is either.

Sorry.

One of your other threads has specific instructions for letting VBox acquire your host network. You probably should follow that.

StevenC21.

net.setup is a helper script to configure your network.
Its mostly not needed and if you think you need it to install in VBox, your virtual machine is misconfigured in virtualbox itself.

The kernel command line is a list of space separated options passed to the kernel when its loaded into RAM.
They appear in grub.cfg after

Thanks Ned. So, what is the package called for me to install? Sorry, I'm new.

Very new.

StevenC21,

When you follow the handbook, how far have you got?

Well, I'm stuck at installing the bootloader. I accidentally formatted it as ext2, and I am having EVEN MORE issues unmounting it to format it FAT. I don't know whats happening lol.

StevenC21,

Understand that Virtualbox provides a whole virtual PC. BIOS, all the hardware ... everything.
Nothing you see in the guest bears any relationship to any real hardware installed in your PC.
That's somewhat simplistic but its a good enough approximation for now.

ext2 is fine in VBox as it will use BIOS by default.
vfat is only required for your EFI partition if you actually use EFI.

What does

The command reads:

StevenC21,

I'm not fobbing you off. I'm a noob at VBox also. I thought you were installing on bare metal with sysrescuecd, the preferred way to install on bare metal.
If that were the case you would have had prompts to set up your network using netsetup.

I'm still following so I can I can learn something myself.

Welcome to Gentoo!

Keep in mind, if you have a program running on a mounted directory, Linux will stop you from unmounting that directory until all programs with an open file handle on that directory has closed their file handles or terminated. Make sure you have no windows cd'd to that directory else you won't be able to unmount.

However yes if you're using MBR boot which is likely when using VBox, you do not need a EFI system partition for that VM. Grub will happily boot off of ext2.

StevenC21,

All of it please. Especially the Disklabel.
We are trying to work out if you are using EFI or not. I suspect not, once its confirmed, the way forward is to not tell grub to use EFI.

You can mix BIOS and GPT, mostly but don't. BIOS and MSDOS is easier.
If you use UEFI, you must use GPT.
Virtualbox defaults to BIOS but it can do UEFI if you configure it that way.

Alright. Is there a way I can help in determining that?

Sorry I really am trying to understand, but I made the jump from 3 months of Linux Mint experience here, so...
