[systemd-devel] [PATCH 6/7] mount: filesystems mounted in the initrd should not conflict with umount.target in the real root

[Colin Walters]

First, thanks for working on this, most of these patches look sane to
me.

But it annoys me that we're propagating this hardcoding in the new code
too.  How about we make systemd inspect /proc/self/mountinfo *very*
early on at boot when it starts, and ensure skip unmounting these, under
the assumption they'll be taken care of either in the initrd, or by the
final kill spree?
