Line 38:
The split between /bin and /usr/bin was because they (Kernigan, Ritchies, Thompson, et al) ran out of disk space on the pack (UNIX was written on a PDP!) that had /bin, so they made /usr/bin. See http://lists.busybox.net/pipermail/busybox/2010-December/074114.html which was referenced from http://www.osnews.com/story/25556/Understanding_the_bin_sbin_usr_bin_usr_sbin_Split/

:That was the original split. The directory layout was changed in SunOS 4.0, with <tt>/sbin</tt> and <tt>/usr/sbin</tt> and </tt>/var</tt> being introduced, and with, as I remember, a bunch of stuff moved from <tt>/bin</tt> to <tt>/usr/bin</tt>. Diskless workstations had <tt>/bin</tt> on a per-machine root file system and <tt>/usr/bin</tt> on a shared read-only <tt>/usr</tt> file system, so they moved as many programs as possible to the shared <tt>/usr/bin</tt> and moved all ''writable'' files from the read-only <tt>/usr</tt> to a per-machine writable <tt>/var</tt>.
