Hi,
we noticed a problem concerning loop mounts on locations that
have to be mounted before. E.g. consider the following situation,
a NFS server exporting a cd image, which we want to loop mount
locally to get access to the content:
auto.master:
/cdimage auto.cdimage
/cdcontent auto.cdcontent
auto.cdimage:
foo nfsserver:/cdimage/foo.img
auto.cdcontent:
foo -fstype=auto,loop :/cdimage/foo/foo.img
The access to /cdcontent/foo will fail, when /cdimage/foo is not
mounted before, because spawn_mount does not use SPAWN_OPT_ACCESS
in this case.
The patch below fixes this problem.
