pmb: display note when chroot is still active
It is unexpected for quite a lot of people, that the chroot folders are still mounted when a pmbootstrap command has finished. With this commit, it will let the user know explicitly:
NOTE: chroot is still active (use 'pmbootstrap shutdown' as necessary)
Close #1524 (closed)
How to test
-
pmbootstrap shutdown
should not print this message -
pmbootstrap chroot -- cat /etc/issue
and similar should print the message
