Hello.
Glad to see that someone take this project in his hands.
I've reported problems some time ago about pre 10 and now I send
letter with attachments that I was sending to the list.]
Best regards. Ruslan.
PS: One patch and expiration problem reports.
I don't have time to write full report that was missed somewhere about
smbfs mounts. I remember that this file system through own design
refresh mount point time to time and without workarounds(hacks) we couldn't
detect who do it user or samba userspace daemon. I've writed patch
that look at command name that cause access refresh to the node, but I
don't think that it's good idea.
Patch is for submounts. Useful when one script(program map) generate -Dkey=value,
then autofs daemon send this values to submounts with program map
types as arguments.--- Begin Message ---
Hello.
I've writed "exec map", that submount another autofs with another program
map, wich return fstype=smbfs.
I've got tree
autofs
autofs submount
smbfs
smbfs
...
autofs submount
smbfs
smbfs
...
...
I use autofs4 protocol, autofs4 and smbfs compiled staticaly.
Expiration problem occur. Smbfs mounts never unmount.
Autofs submounts expire ok, when I don't have third level(smbfs mounts).
Log at the end of letter.
May be I've missed something in configuration, but I don't think so.
I'll try same on 2.4.20 tonight.
Best regards, Ruslan.
PS: Something wrong with my email and Autofs mailing list, my letters
don't appear on the list, but mailman said that I'm subscriber.

Hello, Peter and other.
Updated version. Uses environment and don't overwrite exist.
Best regards, Ruslan.
PS: Any comments and corrections are wellcome. And if it will be in
the tree, I'll write patches to documentation.

Hello, Peter and other.
1) Problem with unmounting during multi expire.
When we have to form list of mountpoints from mtab and fstab, we
compare all records with path. Path contains '//' and all requests
to strcmp fails. First solution is test ap.path in main() for '/' at
end and delete it. I've looked at all places where we use ap.path in
automount.c and think that this solution will be OK.
2) Second problem is smbfs user space daemon that support connections.
As I understand it pereodicaly calls SMB_IOC_NEWCONN and
in result we have call of udate_usage on the mount point. Mount point become
allways in use and never expire.
In the result of two described problems I have autofs nodes which
never expire and automount daemon that I can't stop with script.
All test was done under 2.5.69, autofs4-pre10, Slackware 8.1.
