Thank you Tom Horsley for all your brilliant insights, and especially this one. I have taken your 'locate-user-daemons.c' program, lock, stock and barrel, stirred with some other condiments and come up with this alternate /usr/local/bin/reboot script that works for me: $ cat /usr/local/bin/reboot # Precede normal reboot command with unmounting of nfs mounts # and stop other impediments to progress /usr/local/bin/nfsumount /usr/bin/pkill -9 gkrellmd /usr/local/bin/locate-user-daemons | /bin/bash -i systemctl reboot where /usr/local/bin/nfsumount contains: # Forcibly umount all autofs-mounted filesystems mount | grep /net/ | sed -e 's/.*on //' | sed -e 's/ .*//' | sort -u | tac | while read fn; do umount -fl -t nfs $fn & done Your simpler 'umount -l -t nfs -a' works for mounts listed in /etc/fstab, but not for autofs-mounted filesystems, I believe. I (re)discovered that gkrellmd takes a full 90 sec to be stopped by systemd, but no time at all by pkill; I added that. As you say, more may turn up. Now the 'reboot' command makes my systems shut down smoothly, reliably and quickly, as proper Linux systems should. -- David A. De Graaf DATIX, Inc.
