Subject: History of Lazy and Force unmouting
Date: Mon, 30 Oct 2017 16:41:12 -0500 [thread overview]
Message-ID: <1509399672.6057.30.camel@gmail.com> (raw)
All,
I was hoping to get some background on why the util-linux umount
command doesn't allow lazy unmounting (the -l flag) to be combined with
force unmounting (the -f flag). If both flags are specified, umount
only passes MNT_DETACH to the kernel instead of MNT_DETACH | MNT_FORCE.
I looked through the kernel code, and it appears that the two flags
are orthogonal, so you *should* be able to specify both? I tried
looking back in the git history of util-linux, but it appears to have
been that way since support for lazy unmounting was added in 2006.
Thanks,
Joshua Watt
