The command umount -a -O _netdev does _not_ umount anything, despite an /etc/fstab with the likes of ... alpha:/var/mail /var/mail nfs _netdev,soft,tcp ... The "mount -a -O _netdev" command works as expected. However, the /run/mount/utab files is empty, and I was unable to get the "umount -a -O _netdev" to work as advertised. Running it with "--verbose" flag merely confirmed that everything was being ": ignored". I have a physical /etc/mtab (not symlink), and the "_netdev" option is missing from /etc/mtab file, but that's probably expected??? If I manually add it (_netdev) to /etc/mtab, then the umount -a -O _netdev does work. But /run/mount/utab is empty. Trying to step through the code gets pretty brutal, and the *fs population is still hidden inside some macro...and I can never find where the /run/mount/utab is even being parsed in the umount code-path. This is with a root-over-NFS setup, in case that matters. Probably shouldn't. Kernel is 4.3.0. Is this a regression? Seems there were issues before...wondering if it re-surfaced. -- ### Any similarity between my views and the truth is completely ### ### coincidental, except that they are endorsed by NO ONE ###
