They are using XZ Utils-4.999.9beta, but that may not make a difference.
There are a lot of programs that can go into /bin. What about wget?
zip? vim? On the other hand, some files in /bin seem somewhat
arbitrary. Whay is tcsh there? time? date?
At one time we wanted to make /sbin and /bin as small as possible
because of disk space. Mine are about 5M each. /lib is 16M. The
smallest disk you can buy new is probably 40GB ($17). You can even get
a 1G thumb drive for ($5). Today size is really a non-issue.
We might want to mount /usr from another system so we can update all
systems at once. To me that is another disk size issue that is
obsolete. rsync is probably easier than nfs mounting. I would think
that very few people mount /usr remotely any more.
With that in mind, I am inclined to put newer utilities like xz in
/usr/bin.
