IIRC, Linux had two different shared library implementations?  I haven’t looked, and don’t remember the details, but it might have been linked to the switch from a.out to ELF for executables?  IIRC, the pre-ELF shared libs were a hack on the a.out executable format.

Yes. Those were the SunOS like ones, but with weird address location quirks.


Not sure where that fits into the /etc vs. /sbin timeline.  ISTR Linux was somewhat inclined away from the BSD way of doing things (in favour of Solaris/SVR4).
