I remember way back in the early years of the Third Age, I had to write a process accounting system that supported all kinds of Unices (HP-UX, AIX, Solaris, FreeBSD, Linux ...). And you're right, there's a plethora of other options other than procfs, although IIRC, Linux wasn't the only one I had to support with that variant. Wasn't Solaris one of them?
