[TUHS] Quick Question: Early Filesystems and Name/Metadata Separation?

[Douglas McIlroy via TUHS]

Strachey and Stoy independently invented the same idea at essentially
the same time.
Their operating system, OS1, went into operation before Unix but
didn't get a file system until OS4, in April 1970. So Unix beat it by
six calendar months, but neither influenced the other.

OS6 was published in The Computer Journal in 1972, ahead of Unix.
Source with commentary a la Lions was available. Yet Unix got the
world's attention. Unix was compiled to machine  language for the
PDP11, while OS6 was compiled to interpreted code for the Modular One
made by Control Technologies Limited. Unix had time-sharing, while OS6
was single user. And finally Unix was American, while OS6 was British.

Later there was a similarly accidental "race" to port the two
operating systems. I'm not sure whether Wollongong or Oxford won.
