Hi there. I just got to test it. It ends up with an error:

$ make -f udev-lfs-186/Makefile.lfs

It's x86 LFS.

Other thing that I dislike is shipping .la file. Those files are 
UNNECESARY in every context. You are not building udev with libtool so 
that file is pointless. Just look at files that don't use autotools, 
they don't have .la files, but they work very great. BLFS talloc, mysql, 
most packages that use cmake don't have .la files, but work  very well.

Also, shipping rules in the archive is really nice, avoids having 2 
archives. I would suggest you look at Debian's write_dev_root_rule. That 
one had to be started before udevadm settle and after udevd. It symlinks 
/dev/root to whatever partition that is set as root partition (/). I had 
some problems with grub-install without that one. Also with 
grub-mkconfig ...
