From ebc7f823c0013dfe7fcefe82db48bf4832f5dcec Mon Sep 17 00:00:00 2001 From: Thomas Renninger Date: Fri, 27 Sep 2013 20:10:39 +0200 Subject: [PATCH] dracut: Implement ACPI table overriding An example config file for this feature could be: /etc/dracut.conf.d/03-acpi-override.conf with this content: acpi_override="yes" acpi_table_dir="/etc/dracut.conf.d/acpi_tables" Then all files ending with *.aml will be put into the early cpio (kernel/firmware/acpi) and will be used to replace the BIOS provided tables if the kernel supports this feature.
