Subject: [PATCH] dracut-systemd/dracut-cmdline.sh: Don't error out if there is
|
|
|
18971c |
no root= argument.
|

|

Thanks to systemd's gpt-auto-generator [0] (which implements the Discoverable
|
|
|
18971c |
Partitions Specification [1]), it is no longer necessary to always specify the
|
|
|
18971c |
root= argument.
|
|
|
18971c |
|
|
|
18971c |
However, dracut would still refuse to boot if there was no root= argument (or
|
|
|
18971c |
if it was set to the special value "gpt-auto" [2]). This commit stops dracut
|
|
|
18971c |
from aborting the boot process in these cases and simply lets systemd do its
|
|
|
18971c |
magic.
