Well, I saw a link to WHY we have /bin, /usr/bin, /sbin etc. Interesting
read ...
/ was disk0. /usr was apparently originally short for /user, on disk1.
Then the system disk ran out of space, so they created /usr/bin to have
more space. So when they got a 3rd disk, they called it /home and moved
all the user directories across ...
Hmm, from what I managed to gather in various old docs, that "3rd disk" was still /usr2 originally... until SunOS 4.0, which decided to implement a read-only /usr and did some major /usr reorganization – kicked out home directories to /home, logs to /var/adm, crontabs to /var/spool, and so on. And it apparently had "/bin => usr/bin" and "/lib => /usr/lib" symlinks as part of that reorganization, in 1989. (Though it still had a separate /sbin with barely anything except 'init' and 'mount' inside.)
