Workaround: # ln -s lz4c /usr/bin/lz4
(In reply to Dennis Schridde from comment #1) > Workaround: > # ln -s lz4c /usr/bin/lz4 This does not seem to work. I get "unable to mount root fs" when booting. (Apparently the kernel cannot mount the lz4 compressed initrd.) Booting a lz4 compressed kernel (CONFIG_KERNEL_LZ4=y) with a lzo compressed initrd (dracut --lzo) works, though. So the kernel lz4 support apparently works at least for certain usecases.

Created attachment 371184 [details, diff] dracut.sh-pass-the-legacy-flag-l-to-lz4.patch According to [1] initramfs should be compressed with the -l (legacy) flag. Please try the attached patch. [1] https://lkml.org/lkml/2014/2/15/211
Patch fixed the problem. I sent it upstream.
First half of the fix regarding lz4 support: http://git.kernel.org/cgit/boot/dracut/dracut.git/commit/?id=8a2db478defe9cbc60ec9923e39c62d1504a2b45 The other half is a packaging issue of app-arch/lz4 (bug 502176)
