Subject: [PATCH] 99squash: Don't clean up squahfs on isolate

The only time we need to cleanup squahfs manually is on switch root, to

release resource and memory. We've covered that by setting

"Conflicts=initrd-switch-root.target" for squash cleanup service.

On shutdown systemd will take care of squahfs mounts. But for other

isolate, files in initramfs are most likely still required, so don't

clean up squahfs. For example, kdump's emergency handler will isolate

into its own target, if squahfs is cleaned up it will fail.
