[TUHS] Other POSIX Candidates?

[George Michaelson]

its weak thinking on my part, but I always understood the POSIX
branding to be a very explicit nod to this being a stamp of approval
on a burgeoning UNIX-varieties ecology.

I do not think VMS, or a DOS derivitive, or PICK was a serious
consideration except perhaps in a post-fact rationalisation.

1 let's invent our own
2 let's not thats too stupid
3 so all the mainframe OS targetting IBM are not really much more than
JCL or what MIT and Stanford do and anyway
4 nobody buys anything but minicomputers now and they all run versions
of unix but
5 porting is a royal pain.
6 ok so lets pick a subset of required behaviour to make C and shell work
7 and for good measure is there anyone here who seriously wants VMS? No
8 ok done. Now, for the next 15 committee meetings, lets have many
fine luncheons
9 <time traveller> Richard Stallman is smelly and people don't like him
10 noted. Thank goodness we came up with POSIX independently as a backronym

However, I got thinking on the implications of that phrasing, and have to ask, was there actually a "selection" made picking UNIX over some other candidate, or was it pretty much established from the outset of pursuing a standard that UNIX was going to get standardized?

Did any other OS contend for this coveted honor?
