Since commit 0722b35934, the root mountpoint is
unconditionnally turned to slave which breaks units that are using explicitly
MountFlags=shared (and no other options that would implicitly require a slave
root mountpoint).
Here is a test case:
$ systemctl cat test-shared-mount-flag.service
# /etc/systemd/system/test-shared-mount-flag.service
[Service]
Type=simple
ExecStartPre=/usr/bin/mkdir -p /mnt/tmp
ExecStart=/bin/sh -c "/usr/bin/mount -t tmpfs -o size=10M none /mnt/tmp && sleep infinity"
ExecStop=-/bin/sh -c "/usr/bin/umount /mnt/tmp"
MountFlags=shared
$ systemctl start test-shared-mount-flag.service
$ findmnt /mnt/tmp
$
Mount on /mnt/tmp is not visible from the host although MountFlags=shared was
used.
This patch fixes that and turns the root mountpoint to slave when it's really
required.
