Actually that should not be so difficult to set up. You can use program
called "schroot". It mounts the real folder (/home, /dev, /proc etc) to
chroot using fstab-like file (see /etc/schroot/mount-arch32) and it
copies some essential files (like /etc/shadow and /etc/passwd) to the
Additionally, I think you don't need access to full /, just to /etc,
and /proc since that's all where the program can get any useful info or
where any essential data to be watched over are located. If I'm wrong,
it's not a problem to mount the folder to the chroot filesystem.
The rest of the chroot's filesystem can contain whatever you want.
Actually I believe that it should work even when you would have only
the libs that the program is linked against and some applications that
the program needs to run, you don't even have to install kernel, udev,
I'd recommend not to even use pacman to set up the chroot, but use RPM
to set it all up from the main system, something like:
rpm install base-system --root=/home/chroot
(I don't know how to use rpm, just to show the idea)
and then enter the chroot using
schroot -c my_chroot
and then just start the application from the chroot.
