Yes, but I'd like to specify the file containing the filesystem directly
as block-device, avoiding the preliminary setting up of a /dev/loopN
device with losetup, just like "mount" does with the "-o loop" option.
So, if I have the filesystem in a file, say /srv/filesystems/devel.img,
I'd like to use this configuration:
[devel]
type=block-device
device=/srv/filesystems/devel.img
mount-options=-o loop
and let schroot just call "mount /srv/filesystems/devel.img -o loop
${DEST}" without checking if /srv/filesystems/devel.img is a block
device.
Currently I have to manually mount the filesystem using a 'directory'
chroot type or I have to use losetup to add the /dev/loopN device before
calling schroot.
Thanks for the quick reply!
