Disk size is not an issue (I am running a linux box with a 250 MB disk that
don't want to die)
I similary think that merging /usr could simplify the build process.
util-linux-2.22 produce some <****> libtool warnings because of the split
between /lib and /usr/lib.
I haven't yet tracked why the behavior is different than 2.21.x where those
warnings did not happen.
I blindly hide 46 of 48 libtool warnings doing _before_ running make :
touch /usr/lib/lib/{libblkid,libblkid,libmount}.la
This issue should not happen if /usr is merged.
Everytime you don't use the path that is used by the big distro, you will be
hit by issues on untested path.
Then it is a question of effort to support the choice you made.
You already know that with the udev debacle.
I have been hit too by using regular /etc/mtab (not using symlink to
/proc/mounts) with util-linux-2.22.

I am removing gradually the .la files when upgrading packages when Fedora do
that in the spec file.
I do that before the end of each package compilation, so the list of installed
files is cleaner and easier to read.
That should be done at 80% actually on my build system.
