Without this commit, the root OpenRC service remounts all mounted
filesystems (except /) with the options defined in /etc/fstab via
fstabinfo. It is presently unclear to me why / was excluded from
remounting in 497ff7ee41 and unfortunately
neither the commit nor the associated Bugzilla issue [1] provides
further information on this.
At Alpine, our initramfs does currently not remount / with all options
defined in /etc/fstab [2]. As part of the discussion on the Alpine side
of things we wondered why OpenRC does not remount / since this would be
the easier solution for us. For this reason, this commit changes the
behavior of the OpenRC root services accordingly to also remount / with
the options defined in /etc/fstab.

This fixes #533.
