Here is how I prevent data accidentally being written to a unmounted
mountpoint. You must first ensure that "/example/mountpoint" is an
empty directory. Then
chattr -V +i /example/mountpoint
so for your example: chattr -V +i /home/me/myth
I started doing this for all my mountpoints after I read about the
immutable bit. See:
man chattr
Re detecting if a disk is mounted, in older versions of fedora, the
package sysvinit-tools provided the '\bin\mountpoint' command which
implements this. Try:
man mountpoint
to see if it is available on your system.
