Subject: [PATCH] Update ostree/bootc host system check.
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|
|
Content-Transfer-Encoding: 8bit

|
|
|
This changes the is_container() func for _is_bootc_host()
|
|
and updates the logic and message. This should detect on
|
|
all ostree and bootc hosts to date that are not using
|
|
bootc usroverlay or ostree admin unlock for development
|
|
purposes.
|
|
|
|
resolves: #RHEL-49670, RHEL-49671
