Package: schroot
Version: 1.2.0-1
Severity: wishlist
I have an LVM volume which has an actual partition table in it (so that a
snapshot of it can be booted as a Xen VM), and which I want to also be
able to access snapshots of via schroot. Because it has a partition
table, I mount it with the option offset=32256B, and specify in the
schroot configuration
mount-options=offset=32256B
Now, this works well for accessing the source chroot, but for accessing a
snapshot of the volume, schroot fails to pass the offset option to mount,
and fails to successfully mount the chroot.
I've traced this down to the following code in
/etc/schroot/setup.d/10mount:
elif [ "$CHROOT_TYPE" = "lvm-snapshot" ]; then
CHROOT_MOUNT_OPTIONS=""
CHROOT_MOUNT_DEVICE="$CHROOT_LVM_SNAPSHOT_DEVICE"
fi
Now, assuming there's a good reason why the mount options for
lvm-snapshots are cleared (perhaps someone wants different mount options
for accessing the source and the snapshots?), it would be good to have an
option to specify the snapshot's mount options.
If there isn't, I guess the CHROOT_MOUNT_OPTIONS="" line should be deleted
(that's what I've done for now).
