no, don't do that. What if the client doesn't open all printers? Then
you'd leave the smb.conf loading permanently disabled.
I think the correct solution is to either add checks to see if the
share name is valid (it can't be that hard!) or just not ignore the
checks and bear with a possible segv if the reload happens when the
share is deleted.
there is also a 3rd alternative. Samba doesn't allow a reload to
delete a share that is currently in use. (see the call to
lp_killunused() in server.c). You could add a "inuse" flag to a share
and make conn_snum_used() check that flag. Then add lp_set_used() and
