In case of bug report: Expected behaviour you didn't see

Marking a mount point with x-initrd.mount didn't keep systemd from attempting to unmount the filesystem during shutdown.

In case of bug report: Unexpected behaviour you saw

Systemd compalins about not being until to unmount said filesystem.

In case of bug report: Steps to reproduce the problem

The following routine attempts to check for x-initrd.mount in the mount options:

static bool should_umount(Mount *m) {
MountParameters *p;

    if (path_equal(m->where, "/") ||
        path_equal(m->where, "/usr"))
            return false;

    p = get_mount_parameters(m);
    if (p && mount_test_option(p->options, "x-initrd.mount") &&
        !in_initrd())
            return false;

    return true;

}

However, p->options is derived from /proc/self/mountinfo -- the x-* flags are not sent to the kernel and therefore they will NOT appear in /proc/self/mountinfo.
