Consider the case where a previously elevated mount was not unmounted correctly. `mount | grep $(basename $APPIMAGE)` would evaluate to a multi-line string, and therefore `awk` will perform its work on *each* line separately, usually returning something like: ``` /tmp/.mountXXXX /tmp/.mountYYYY-elevated ``` We then pass `$mountpoint` to `mkdir -p`, which evaluates to: ``` mkdir -p /tmp/.mountXXXX /tmp/.mountYYYY-elevated ``` Therefore `/tmp/.mountXXXX` gets created, and `/tmp/.mountYYYY-elevated` is ran as an executable, causing all sort of cryptic errors to come out. This can be even worse, since the third column of a `mount` line is not always a path, so the errors make even less sense.
