Subject: [PATCH] dracut.sh: disable lsinitrd logging when quiet
|
|
|
adad6c |
|
|
|
adad6c |
Currently in Fedora/RedHat dracut installs its fedora.conf.example
|
|
|
adad6c |
as the default config file, in which sysloglvl is set 5. This leads
|
|
|
adad6c |
to maxloglvl=5 in dracut calls, making unnecessary lsinitrd calls
|
|
|
adad6c |
during initramfs builds by kdump.
|
|
|
adad6c |
|
|
|
adad6c |
This patch disables lsinitrd logging when --quiet option is given,
|
|
|
adad6c |
which is controlled by maxloglvl only before. This will speed up
|
|
|
adad6c |
dracut image building as the following if --quiet is used in kdump:
