*BSD ignored most FHS agreements from 1987 and unfortunately Linux followed 
this.

See my recent post for the real historical background.

/sbin was created for SunOS-4.0 for the few (at that time static) binaries 
that are needed in order to bootstrap the multi-user mode.

At the same time, /usr/etc was renamed to /usr/sbin.

There have been some other changes before 1987, that allowed to have /usr 
read-only - as required by the berkely "nd" driver that introduced the ability 
to boot diskless clients. These changes however have been introduced as a hack 
and many symlinks have been introduced to work around files that have been on 
/usr but need to be writable (e.g. /usr/spool).

With SunOS-4.0 and the FHS UNIX summit in 1987, /var and /opt have been 
introduced.
