Run Yaourt as user inside 32bit chroot?

biatchi · 2008-08-22 02:12:33

I have a 64bit system and have a 32chroot setup as per the wiki instructions. Everything works brilliantly except that Yaourt runs as root and I want to build firefox-spookyet. Does anybody know how I would go about doing this?

Come to think of it, Is it safe to run Firefox from a chroot? Htop says firefox is runing as biatchi but also that root executed

/bin/su -p biatchi -c firefox

Is that safe?

I use the dchroot command to run things from chroot, so yaourt, for example, can be run like this:

dchroot -d 'yaourt -Syu --aur'

I actually have this aliased to something more convenient.

The problem is, I just noticed that the dchroot package was removed from the repos and schroot (the package that's supposed to be its replacement) doesn't seem to be in any of the repos, so I'm not sure what's going on there...

EDIT: uhm, I don't think I've read your post carefully enough. You should be able to do "su [username]" when within chroot, which would then allow you to use makepkg as regular user. I'm not sure is you need to have your /home --bind mounted withing the chroot for this to work or not.

I actually log into chroot as regular user, I have this alias in my .bashrc:

alias arch32="sudo chroot /opt/arch32/ /bin/su - filip"

You'd need to replace "filip" with your username, of course.

That works brilliantly thanks

Htop still shows root executing

/bin/su -p biatchi -c firefox

if I do dchroot -d firefox but it doesn't if I log into my chroot and just type firefox, I guess that isn't anything to worry about?

On my system htop shows that commands "su" and "dchroot" are running with root privileges, but firefox is running with regular user privileges so it should be all good, I think, though I'm not a security expert so don't trust me on that

Also, if you look carefully, the command /bin/login, on which almost all other processes such as X, window manager and so on depend is also running as root -- this seems to be analogous to the relationship between su/dchroot and firefox. If you switch htop to "tree view" in preferences it all sort of becomes more clear.

Hmmmm....I tried this alias and also tried 'su username' within the chroot. Each time I get an error saying

/bin/su: incorrect password

Any ideas why?

[Edit -- solved]Oops -- above part solved by running /sbin/pwconv inside the chroot. Apparently something got corrupted or I missed step when I installed the chroot.

Does anyone know when or where I can download dchroot or schroot? They're still missing from the repos.

Thanks!
Scott

Save this as "PKGBUILD" somewhere and run makepkg -cis in the same directory.

Thanks very much for the dchroot PKGBUILD! Hopefully the new schroot makes it in to the repos soon.

I added a comment to schroot aur page -- hopefully this will be solved soon.
