Subject: [PATCH] Add grub-get-kernel-settings and use it in 10_linux
|
||
|
|
|
||
|
|
This patch adds grub-get-kernel-settings, which reads the system kernel
|
||
|
|
installation configuration from /etc/sysconfig/kernel, and outputs
|
||
|
|
${GRUB_...} variables suitable for evaluation by grub-mkconfig. Those
|
||
|
|
variables are then used by 10_linux to choose whether or not to create
|
||
|
|
debug stanzas.
|
||
|
|
|
||
|
|
Resolves: rhbz#1226325
