Subject: [PATCH 107/125] 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.
