lf server prevents unmounting drives, etc.

[LukeSmithxyz]

Issue:

1. have a removable drive mounted
2. open lf in a directory in the mounted position
3. close lf/lf window
4. attempt to umount the drive and it will not unmount

If you killall lf to kill the lf server you will be able to unmount it (or if you run umount -l), but normal umount will hang/fail.

This has actually be going on for years and I put up with it (lol), but I figure it bothers someone else too.

This can be a problem during shutdown.

Does set autoquit on in lfrc fix the issue?
