Hi!
When you just think it could not get any better…
Threefold:
unmount issues with multiple-device Filesystems like btrfs #14454
https://github.com/systemd/systemd/issues/14454
btrfs multiple devices confusion: automatically unmounted /home, clobbered
ssh session #14674
https://github.com/systemd/systemd/issues/14674
systemd attempted to unmount filesystem after btrfs replace on LUKS #19393
https://github.com/systemd/systemd/issues/19393
Really, what is even wrong with your attitude, systemd developers?
Unmounting a filesystem behind the user's back? Seriously?
Probably still unfixed:
https://pagure.io/fedora-btrfs/project/issue/64
Again I am so happy not using systemd.
It is ridiculous. If you add complexity, you add errors.
And if you add (insane) policy you add even more errors.
Best,
