Revert "Simplify shutdown, no need for workarounds to remount / read-only"

Browse Source 
This reverts commit 7c42986800 since we
seem to still need this werid thing on some systems.  The key seems
to use 'any' device at remount[1].  Anyway, the key issue before was
the noisy output, but like Debian we'll just redirect to /dev/null.
