Subject: [PATCH] Use existence of /etc/initrd-release to detect initrd.
|
||
|
|
|
||
|
|
Since v183, systemd has used the existence of /etc/initrd-release to
|
||
|
|
detect if it is running in an initrd, rather than looking at the magic
|
||
|
|
number of the root filesystem's device. It is time for mdadm to do the
|
||
|
|
same.
