cancelling with CTRL+C need to be followed by umount /run/bees/mnt/$UUID #281

btw. I just tried the current beesd script and starting like beesd ..: After cancelling with CTRL+C I always need to umount /run/bees/mnt/bab5... for the next run. Is that intended?

@Zygo would be nice if bees was fixing itself on die

Putting this at the beginning of beesd should work:

#!/bin/sh

if [ -z "$UNSHARE_DONE" ]; then
        UNSHARE_DONE=true
        export UNSHARE_DONE
        exec unshare -m --propagation private -- "$0" "$@"
fi

The drawback is that this duplicates the systemd namespacing, and requires the namespace privilege in the script to work. Maybe some additional checks to see if it's running under systemd and skip the extra unshare call?

Hi, is this going to be fixed in the mail release?
