Indeed so. Linux had a filesystem type named umsdos that layered a raft of non-native semantics on top of the FAT on-disc data structures with the use of magic '--LINUX.---' files.

I think that we can safely say in the 2020s that, across the world of Windows NT, BSDs, Linux, et al., use of the FAT filesystem format has been relegated to edge cases like some boot volumes (e.g. the EFISP) and some data interchange, and isn't in general use for system volumes.

If you look around you should still be able to find Luke Mewburn's paper on #MewburnRC .

Similarly, what Linux people erroneously call "sysvinit" is actually van Smoorenburg init+rc created (by Miquel van Smoorenburg) for Minix in 1992.

It's not from #Unix System 5 at all, as that had obsoleted R3's init+rc system years before 1992 and gone on to the AIX SRC, and the SAF, SAC, ttymon, SMF, and stuff still in #Illumos today.
