From df58ab6257ff2c688432d3cde159538419f85769 Mon Sep 17 00:00:00 2001 From: Ziyue Yang Date: Wed, 23 Aug 2017 11:23:34 +0800 Subject: [PATCH] dracut.sh: disable lsinitrd logging when quiet Currently in Fedora/RedHat dracut installs its fedora.conf.example as the default config file, in which sysloglvl is set 5. This leads to maxloglvl=5 in dracut calls, making unnecessary lsinitrd calls during initramfs builds by kdump. This patch disables lsinitrd logging when --quiet option is given, which is controlled by maxloglvl only before. This will speed up dracut image building as the following if --quiet is used in kdump: 1) Before this patch $ kdumpctl stop; touch /etc/kdump.conf; time kdumpctl start kexec: unloaded kdump kernel Stopping kdump: [OK] Detected change(s) in the following file(s): /etc/kdump.conf Rebuilding /boot/initramfs-4.13.0-0.rc1.git4.1.fc27.x86_64kdump.img kexec: loaded kdump kernel Starting kdump: [OK] real 0m26.824s user 0m9.958s sys 0m15.106s 2) After this patch $ kdumpctl stop; touch /etc/kdump.conf; time kdumpctl start kexec: unloaded kdump kernel Stopping kdump: [OK] Detected change(s) in the following file(s): /etc/kdump.conf Rebuilding /boot/initramfs-4.13.0-0.rc1.git4.1.fc27.x86_64kdump.img kexec: loaded kdump kernel Starting kdump: [OK] real 0m20.420s user 0m8.385s sys 0m10.468s Signed-off-by: Ziyue Yang --- dracut.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/dracut.sh b/dracut.sh index 62e53b73..d7459d06 100755 --- a/dracut.sh +++ b/dracut.sh @@ -1688,7 +1688,7 @@ fi dinfo "*** Creating image file done ***" -if (( maxloglvl >= 5 )); then +if (( maxloglvl >= 5 )) && (( verbosity_mod_l >= 0 )); then if [[ $allowlocal ]]; then "$dracutbasedir/lsinitrd.sh" "${DRACUT_TMPDIR}/initramfs.img" | ddebug else
