This only serves to remove a mounted directory after "yanking" the device. It
doesn't really do anything useful though, you'll still get corrupted
filesystems, because Linux is way too lazy in writing out dirty data.
Proper solution would be to have the system mount a removable device as
read-only, and promote it to r/w once someone tries to write to it. And then
after a timeout, it should go back to readonly.
Supposedly, "autofs" can accomplish this, but I've never met anyone who got
that to actually work.
Kind regards,
