Subject: [PATCH] shutdown: fix arguments to /run/initramfs/shutdown
|
|
|
|
Our initrd interface specifies that the verb is in argv[1].
|
|
This is where systemd passes it to systemd-shutdown, but getopt
|
|
permutes argv[]. This confuses dracut's shutdown script:
|
|
Shutdown called with argument '--log-level'. Rebooting!
|
|
|
|
getopt can be convinced to not permute argv[] by having '-' as the first
|
|
character of optstring. Let's use it. This requires changing the way
|
|
non-option arguments (in our case, the verb) are processed.
|
|
|
|
This fixes a bug where the system would reboot instead of powering off.
