schroot doesn't make bind mounts for a plain chroot

[Martin Pool]

Binary package hint: schroot

schroot with the configuration quoted below doesn't seem to run its setup scripts, and therefore does not bind-mount the filesystems mentioned in /etc/schroot/mount-defaults. I can't work out why. A comment in the scripts hints they may just not be run for plain chroots, but I can't see why that is useful, and I can't see that it's documented.

From the schroot.conf manpage:

   Plain and directory chroots
       Chroots of type ‘plain’ or ‘directory’ are directories accessible in the filesystem.
       The two types are equivalent except for the fact that if run-setup-scripts is set
       to ‘true’ for ‘plain’ chroots, filesystem mounting is disabled.

Therefore I believe schroot is functioning as designed.

I use schroot for my dev chroot (where I work on packages) and it bind mounts my directories as expected.
Looking at the wiki article for using schroot for a LP chroot, I guess you missed adding "type=directory" to your schroot.conf stanza (default is type=plain). And as Max wrote 'plain' schroots don't bind mount.

You're right, I didn't understand this was controlled by type=
