I guess my blurb about the JFS filesysytem was a little too general in nature (I must admit, it almost reads like a commercial). I was speaking primarily from my own personal experiences. I myself have used ext3, Reiser3 and XFS - all of those BEFORE switching to JFS, so, believe it or not, I DID indeed mean that IMHO the jfs fs is better OVERALL. I will readily admit that if you expect a possible need to resize the partition at some future date, the JFS is not what you want to use. But to me, that's the one and ONLY disadvantage in picking JFS.
When I used ext3, I had no real problems to speak of, as long as no fsck or "tuning" of any kind were needed. For those of you who are TRULY "tech-savvy", ext3 is fine (though rather slow and very "picky" about some things). But for the "average" user, the "man" files are a bad joke (I used to get headaches trying to understand them). And - if e2fsprogs is so good - then why (apart from the new ext4) do they have so many darned "upgrades"? (You might ask that about XFS as well).
As you can surmise by now, I am no "geek" (no pun intended, Granny) - just a rather typical "intermediate" user (I switched from Bill Gates' crap in February of 2006). I did have some file corruption problems with both Reiser3 and XFS, and broken symlinks troubles with XFS which is what I used for Vector-5.8. The manuals for Reiser & XFS are "bad news" compared to the clear, short, simple and UNDERSTANDABLE man files that come with jfsutils. I don't doubt that they're no real problem for "pro's", but please remember that the experts are a small minority of today's Linux users such as myself. Also, since switching to JFS in 2008 (almost 2 full years ago), I have gone through several power outages here in stormy Arkansas, several fsck's, I've formatted & used several flash (USB) drives with JFS, and I have NEVER yet experienced any filesystem slowdowns, corruption or problems of any kind - whatsoever.
As far as current JFS availability on Vector, quite frankly, I haven't tried a Vector release for several months now because the last time I did (with a then-current Live CD), I couldn't even mount my hard drive or flash drive for "repairs" due to the fact that they were JFS-formatted. As a result, I simply gave up on you for the time being (maybe you can now understand why I cared enough to write my first post). I guess when a guy's been "burned", he thinks twice before lighting ths same match a second time!
If you REALLY care about making & keeping Vector "user-friendly", then the jfs filesystem is simply as good as it gets. It's virtually identical to both Reiser and XFS in terms of space efficiency (compare that to ext3), it's smaller, simpler, bug-free (as far as I can see), fast, very reliable AND the "man" files are written for relative tech-dummies like me. What more can I say?
