Anybody have any opinions on PFS, based upon *actual long-term usage*?
I've used PFS, AFS, PFS2, PFS3 7-8 years at least, iirc even longer. Started with A1200, and now I use it in Pegasos II. I've never had any serious problems with it (like data lossage). I learnt years ago that using write disk cache app was a bad idea though (at least if it reorders disk writes, RO cache was ok though).
ATM I have 350GB data on PFS3 partitions.
PS. I once tried SFS. It would corrupt itself after writing 20GB data in one go. Tried it 3 times, nuked every time. Thus I haven't used SFS a lot myself, so I can't give you any ideas how well SFS and PFS3 compare.
I don't know how long the FileNote can be though.
79 chars, the standard length.
Regarding version numbers. That is how standard version numbers work. It's no decimal point, but version/revision separator:
version.revision
