Automounter stops after reload signal.

(I've sent this earlier to the autofs maillist but it doesnot appear 
there, I do not get a copy also myself)

Hello,

I've been working on a construction which adds an autofs managed
mountpoint to the homedirectory, when:
a. an usb device or more than one is detected when logging in
b. an usb device is plugged in during a session

This looks like:

/home/sbon/Connections

is the base directory for all kinds of connections (network, all kind of
hardware)
Earlier I've been working on a construction to create a browseable
network map here, also with autofs.
Network resources like SMB shares, FTP servers and SSH access is
possible. (SMB via cifs, FTP via curlftpfs/FUSE, SSH via sshfs/FUSE).
Access to Novell networks should also be possible.

Now about devices. When I add a device during my session, the (virtual)
directory Devices is added, and therein my USB stick:

/home/sbon/Connections/Devices/USB_DISK_Pro

Other devices should also appear in this directory.
I do not have published this yet anywhere, but it is simular to the one
you can find here:

http://www.gentoo-wiki.info/Autofs#UDEV_with_autofs

The big difference with my construction is that the mountpoint is *in*
the users homedirectory, not in /media: direct accessible for users from
their homedirectory, where going to a "foreign" place like /media is not
that userfriendly.

Now I've got the following situation:

my mastermap looks like:

/mnt/sd /etc/autofs/auto.sd --timeout=50

+/var/run/autofs/auto.master


and /var/run/autofs/auto.master:

/home/sbon/Connections/Network
/var/run/autofs/session/auto.network.map.sbon --ghost
/home/sbon/Connections/Devices /var/run/autofs/session/auto.usb.map.sbon
--ghost

the automaps are dynamically created maps:
/var/run/autofs/session/auto.usb.map.sbon:

USB_DISK_Pro -fstype=auto :/dev/disk/by-uuid/6891-3786

and /var/run/autofs/session/auto.network.map.sbon:

"FTP" -fstype=ftpfs \
       /192.168.0.1 ://192.168.0.1 \
       /ftp-stud.fht-esslingen.de ://ftp-stud.fht-esslingen.de
"Windows Network"
-fstype=cifs,credentials="/var/run/safe/sbon/latest/mount.smb.cred" \
       "/BONONLINE/ROUTER/sbon" -rw,ip=192.168.0.1 "://ROUTER/sbon" \
       "/BONONLINE/ROUTER/bononline" -rw,ip=192.168.0.1

       "/BONONLINE/ROUTER/ftp" -rw,ip=192.168.0.1 "://ROUTER/ftp" \
       "/BONONLINE/ROUTER/public" -rw,ip=192.168.0.1 "://ROUTER/public" \
       "/BONONLINE/ROUTER/cwdocumenten" -rw,ip=192.168.0.1

"://LFS20060812/sbon" \
       "/BONONLINE/LFS20060812/bononline" -rw,ip=192.168.0.2
"://LFS20060812/bononline" \
       "/BONONLINE/LFS20060812/video" -rw,ip=192.168.0.2
"://LFS20060812/video" \
       "/BONONLINE/LFS20060812/test" -rw,ip=192.168.0.2
"://LFS20060812/test" \
       "/BONONLINE/LFS20060812/public" -rw,ip=192.168.0.2
"://LFS20060812/public"
"SSH access" -fstype=sshfs \
       "/192.168.0.1" "://sbon@192.168.0.1:/" \
       "/192.168.0.2" "://sbon@192.168.0.2:/"

These maps are created dynamically, by udev (when plugging in a device)
and at login (coldpluggin and the networkmap)
There is a script which is run by udev when a device is removed.

After removal of the usbstick, my maps look like:

/var/run/autofs/auto.master

/home/sbon/Connections/Network
/var/run/autofs/session/auto.network.map.sbon --ghost

The networkmap is unchanged.

After a reload the automounter has stopped. Attached is the relevant
output of the logfile.

This behaviour I get also in siumlar situations. For example, logging in
as sbon, adding a device, then logging in as root in a terminal(konsole
and then su), everything is still ok (the maps above are changed:
mountpoints and maps are added. But when logging out as root, and the
maps are changed again, the automounter stops also.

It looks like the automounter cannot handle the removal of mountpoints
correctly. It will stop.
