Subject: [PATCH] Add detection for ostree-based systems and warn users about
|
|
losing changes
|

MIME-Version: 1.0

|
On ostree-based systems, users can use dnf to customize the
|
|
environment but those changes will be lost at the next ostree-based
|
|
image update. If you want to retain changes between ostree-updates
|
|
you need to make use of rpm-ostree right now.
