using --ghost with 'program' type maps

[Tom Urlings <tom.urlings@gmail.com>]

hi all,
i have been using autofs for a long time now, using it to dynamically gather 
multimedia mounts using aufs locally and across local network..
however, ghosting is not supported for 'program' maps.. which makes sharing a 
autofs mount a bit odd..

example:
server:/srv/multimedia -> automounted locally on server
: uses aufs locally to mount all multimedia type directories on local storage

client:/opt/multimedia -> automounted locally on client
: uses aufs locally to mount all multimedia type directories on local storage 
and on automounted samba shares (also on server)

when server automount is mounted on client, server:/srv/multimedia is mounted, 
but (as spec'ed) ghosting is not performed, giving an empty directory..

looks like the lookup_ghost on client does nothing as there are no cached 
entries from the mapfile (program) available.. same goes on 
server:/srv/multimedia..

could this be easily integrated into the automount source?

i have been looking into it today, but it looks a bit quirky to just 
copy/paste the lookup_file.c:lookup_read_map into 
lookup_program.c:lookup_read_map (with all ancilliaries)..

idea is to have the program maps return a complete 'file' map when given no 
key on the commandline, and to 're-use' the lookup_file.c:lookup_read_map 
functionality in the lookup_program.c:lookup_read_map

do any of you have a direction into where i should start looking?

thanks in advance..

best regards,
