Thanks for the suggestion. I'm using Gnome, and created an executable file /etc/gdm/PostSession/autofsNFS containing: #!/bin/bash if grep -q ':.* nfs[234]\? ' /proc/mounts; then if [ -r /var/run/autofs.pid ]; then Pid=$(</var/run/autofs.pid) [ -n "$Pid" ] && kill -USR1 $Pid fi fi That sends a SIGUSR1 to the automount process if there are any remote NFS mounts listed in /proc/mounts. It seems to do the trick. -- Bob Nichols "NOSPAM" is really part of my email address. Do NOT delete it.
