man/systemd.exec: MountFlags=shared behaviour was changed (fixed?)
The behaviour described *was* observed on Fedora 28
(systemd-238-9.git0e0aa59), with and without SELinux. I don't actually
know why though! It contradicts my understanding of the code, including an
explicit comment in the code.
Testing in a VM upgraded to v239-792-g1327f272d, this behaviour goes away.
Test case:
# /etc/systemd/system/mount-test.service
[Service]
MountFlags=shared
Type=oneshot
ExecStart=/usr/bin/ls -l /proc/1/ns/mnt /proc/self/ns/mnt
ExecStart=/usr/bin/grep ext4 /proc/self/mountinfo
Weird old behaviour: new mount namespace but / is fully shared.
