UFS?

Is this the file system known as 'UFS'? Jnc (talk) 14:03, 7 September 2022 (CEST)

According to some sources, yes, the traditional Unix file system (i.e. before FFS) is called UFS. Others apparently mean something slightly different. Larsbrinkhoff (talk) 21:50, 7 September 2022 (CEST)

I went looking for such sources, and according to Unix File System on Wikipedia (not the most reliable source, but probably an OK start), the ones before FFS it calls 'V6FS' and 'V7FS' (which are basically identical, except that the former has 16-bit block numbers, and the latter 32-bit). Then comes FFS, and various descendants of that are called 'UFS'. They're all roughly the same (they're all based around 'cylinder groups', which came in with FFS), but have varying enhancements.
