lxc doesn't help if the boot process of your guest is broken.
I would recommend chroot for the repair work.
For a one-off job, schroot might not even be worth setting up.
If you want to try an lxc variant once your guest sytem is fixed:
Most of the mount commands from the chroot solution are not needed with
lxc because it runs the guest system's boot process, which mounts the
necessary filesystems based on the guest's /etc/fstab and other knowledge
hard-coded inside the guest system.
Guest machines for libvirt-lxc can be easily set up using virt-manager,
that's what I used here.
It is my understanding that plain lxc offers more features and has to be
set up manually with a config file, but I haven't used it yet.
