Subject: [PATCH] 99squash: Don't clean up squahfs on isolate
|
|
|
e83cdd |
|
|
|
e83cdd |
The only time we need to cleanup squahfs manually is on switch root, to
|
|
|
e83cdd |
release resource and memory. We've covered that by setting
|
|
|
e83cdd |
"Conflicts=initrd-switch-root.target" for squash cleanup service.
|
|
|
e83cdd |
On shutdown systemd will take care of squahfs mounts. But for other
|
|
|
e83cdd |
isolate, files in initramfs are most likely still required, so don't
|
|
|
e83cdd |
clean up squahfs. For example, kdump's emergency handler will isolate
|
|
|
e83cdd |
into its own target, if squahfs is cleaned up it will fail.
