Merging /usr

[Jeffery To]

Hi,

It appears most of the major distros (Debian/Ubuntu, Fedora, Arch,
Solaris) have moved to merge the contents of /{bin,sbin,lib}/ into
/usr/{bin,sbin,lib}/, with top-level symbolic links added for
compatibility.

There is a wiki page on freedesktop.org[1] that goes into the
reasoning, and LWN[2][3] has also written about it.

Is this something we would like to consider as well? It may be too
late for 20.x but this change does appear to simplify things (at least
for package maintainers).

Jeff
