initrd: add unit files needed for basic systemd-in-initrd support This will: * mount all configured filesystems (typically the rootfs on /sysroot) * reload the configuration to pick up anything from the mounted fs (typically /sysroot/etc/fstab) * mount any newly configured filesystems (typically /usr on /sysroot/usr, if applicable) * shut-down and clean-up any daemons running in the initramfs (typically udevd) * switch-root to /sysroot and start the real init For an example of what files should be included in an initramfs based on this see <https://mailman.archlinux.org/pipermail/arch-projects/2013-February/003628.html>.

Description=Switch Root
units: upgrade initrd check Conditions to Asserts It's a bug if an initrd unit is run on the host. Hence let's upgrade the conditions to asserts.

DefaultDependencies=no
units: downgrade Requires= to Wants= Combining Requires= with Before= doesn't really make sense, since this means we are requiring something that runs after us, which logically cannot be fulfilled. Let's hence downgrade Requires= to Wants= so that the ordering is kept but no failure propagation implied.

units: add Wants=initrd-cleanup.service to initrd-switch-root.target (#4345) `systemctl isolate initrd-switch-root.target` called by initrd-cleanup.service kills initrd-cleanup.service itself. Then, initrd-cleanup.service failed and system goes to emergency shell. To prevent this problem, this commit adds `Wants=initrd-cleanup.service` to initrd-switch-root.target. fixes: #4343.

units: make sure initrd-cleanup.service terminates before switching to rootfs A follow-up for commit a8cb1dc3e0fa81aff. Commit a8cb1dc3e0fa81aff made sure that initrd-cleanup.service won't be stopped when initrd-switch-root.target is isolated. However even with this change, it might happen that initrd-cleanup.service survives the switch to rootfs (since it has no ordering constraints against initrd-switch-root.target) and is stopped right after when default.target is isolated. This led to initrd-cleanup.service entering in failed state as it happens when oneshot services are stopped. This patch along with a8cb1dc3e0fa81aff should fix issue #4343. Fixes: #4343
