Minimal Arch install script - EFI/GPT gummiboot with LUKS

altercation · 2012-09-20 08:06:26

Might be of use to others, this is a stripped down non interactive install script for a single disk, three partition, encrypted root & swap install. It uses gummiboot from AUR.

I've been working on using the gummiboot in extra but haven't had success getting it to function, yet.

(Also, I'm working on unifying the install process so that you don't need to manually arch-chroot. Later on that.)

In my script I just prefix each command with 'chroot /mnt', like e.g.

chroot /mnt locale-gen
chroot /mnt mkinitcpio -p linux
chroot /mnt su - martin -c "curl -s http://aur.archlinux.org/packages/dw/dwb-hg/dwb-hg.tar.gz | tar xzC /tmp && cd /tmp/dwb-hg && makepkg -si --noconfirm"

arch-chroot does pass the command line arguments on to chroot but I get some weird failures. with just chroot I can pass a script in the same manner as you use, but with arch-chroot this chokes during mkinitcpio.

FWIW, you can also redirect all those commands to chroot in one go:

chroot /mnt << YEOLDECOMMANDS
locale-gen
mkinitcpio -p linux
su - martin -c "curl -s http://aur.archlinux.org/packages/dw/dwb-hg/dwb-hg.tar.gz | tar xzC /tmp && cd /tmp/dwb-hg && makepkg -si --noconfirm"
YEOLDECOMMANDS

I haden't read your script sorry, and just thought from your post that you didn't knew the "non-interactive chroot method"...

I don't know why it fails with arch-chroot, but why don't you just use chroot then ?

In my script I don't use pacstrap and arch-chroot, but just run the needed commands directly instead. I do that so I don't need to change the script if the aif ever comes back and Dave's install-scripts maybe gets removed ...

As you know, for mkinitcpio not to fail, then you need to mount the pseudo-filesystems first, but as arch-chroot also does that, then I don't know why it fails with it...

Thanks for your heredocs tip btw... I did knew it, but still hadent used it, dunno why

It'd be nice to actually post those failures... if there's a bug in arch-chroot or room for improvement, I'd like to fix it.

Yeah, I did build an installer without pacstrap and arch-chroot as well but then figured I'd try to play nice with the new scripts. They are pretty nice helpers and I think I'll try to get this working with them first, but if I don't I'll go back the plain-old method as you suggest

I think I can get the mkinitcpio build if I export the locale again (I think the env isn't being passed properly) but I still get hung up on my bootloader install. I think it might be my heredoc getting double escaped (the \\ slashes in the EFI path are a nightmare to keep track of in the terms of how many times they are getting escaped... I'd single quote them but I have some variables in them).

I love heredocs

I almost messaged you yesterday on this then figured I should do some more work to make sure I wasn't being dumb about something

Let me figure out if I'm screwing up first then I'll submit or offer up a patch if I can narrow down the problem.

I've updated the github repository with a version that is now working, unified, with arch-chroot. The customization section at the end is messy but it should be clear enough how things work.

@falconindy is blameless and I confirmed that, as I suspected, the problems with arch-chroot were entirely of my own making.
