From b7000adef17a5cce85636e40fa2c2d9851a89e28 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Fri, 20 Dec 2013 16:52:45 -0800 Subject: Don't set the INITRD_COMPRESS environment variable automatically Commit 1bf49dd4be0b ("./Makefile: export initial ramdisk compression config option") started setting the INITRD_COMPRESS environment variable depending on which decompression models the kernel had available. That is completely broken. For example, we by default have CONFIG_RD_LZ4 enabled, and are able to decompress such an initrd, but the user tools to *create* such an initrd may not be availble. So trying to tell dracut to generate an lz4-compressed image just because we can decode such an image is completely inappropriate.
