Are these paths (/usr/home/smb and /usr/home/vhosts/django) separate file
systems on the server from the others?

If they are on the same server file system as one of the other entries,
then the paths need to be added to that entry. You cannot have multiple
entries for the same server file system and exported host/subnet.

For example, if /usr/home/smb and /usr/home/vhosts/django are on
the same server file system as /usr/home/dalroi, then you need
a single entry for the 3 that looks like:
/usr/home/dalroi /usr/home/smb /usr/home/django -mapall=delaroi -network 10.236.150.0/23

At least that's my recollection of it. The format for this hasn;t changed in
ages.

If they are separate file systems on the server (separate mount points in /etc/fstab),
then I don't know what is broken.
