Fixed In Version: mkinitrd-5.1.19.6-68.el5_6.1 Doc Type: Bug Fix
Doc Text:
When creating the initrd file, the mkinitrd utility reads the configuration to determine what kernel modules to load and which module options to use. Previously, the mkinitrd utility only read the /etc/modprobe.conf configuration file. This update corrects this error, and when the /etc/modprobe.conf file does not exist, mkinitrd now attempts to read the configuration from the files located in /etc/modprobe.d/ instead.

Comment 5 Alexander Todorov 2011-04-07 12:03:23 UTC
Tested with instructions from
https://bugzilla.redhat.com/show_bug.cgi?id=564392#c2

and with mkinitrd-5.1.19.6-68.el5_6.1.x86_64:

# echo "alias scsi_hostadapter2 cciss" > /etc/modprobe.d/test.conf
# mv /etc/modprobe.conf /etc/modprobe.conf.back
# mkinitrd -f --nocompress /tmp/initrd-testing.img `uname -r`
Modulefile is /etc/modprobe.d/blacklist.conf /etc/modprobe.d/test.conf
# cpio -t < /tmp/initrd-testing.img | grep cciss
16781 blocks
lib/cciss.ko
