[buildd-tools-devel] Bug#579387: schroot: Please allow to use variables in default/fstab

[Mike Hommey]

Package: schroot
Version: 1.4.1-2
Severity: wishlist

I'm currently using the new unionfs support in schroot, which is an awesome
addition, but it would be useful for my setup to be able to specify variables
in some places of the fstab, so that I don't need to write extra setup scripts.

Currently, I'm removing /home from the default fstab and mount it later with
custom unionfs setup, and I also bind mount /var/cache/apt/archives from the
original chroot, so that it is not part of the unionfs.

It would be much simpler for me (and other users, for that matter), to be able
to specify, say:

/home /home aufs br:${CHROOT_UNION_OVERLAY_DIRECTORY}/home:/home=ro 0 0
${CHROOT_DIRECTORY}/var/cache/apt/archives /var/cache/apt/archives none rw,bind 0 0

(though in my case, there would still be a problem, as
${CHROOT_UNION_OVERLAY_DIRECTORY}/home doesn't exist at first ; does
schroot-mount create mount points when they don't exist ?)

Cheers,

Mike
