Looking backward it hasn't been that much of a FAQ, because (despite what various commercial distros were willing to support for money) as far as the list was concerned btrfs was experimental (and is currently still not fully stable), so the very strong recommendation has always been, and remains now altho the strength of the recommendation is gradually fading as btrfs stabilizes, that users should always run the latest kernel as otherwise they are missing fixes for known problems that may well bite them if they don't. Similarly but not as critically and with some differences for userspace. One difference was that until fairly recently userspace didn't have regular releases, so users of an after all experimental filesystem were expected to run git snapshots either built themselves and updated regularly, or from the distro, provided the distro updated their snapshots at least a couple times a year. Older versions were mainly missing features for the online stuff (as Chris mentioned), and users were told they'd obtain best results for the offline stuff with current live-git (where the master branch was and is release-maturity-only code) or with specific testing patches. Looking forward, however, as btrfs matures and stabilizes and as part of that process the btrfs community and documentation begins to accommodate users who routinely run years outdated code for the stability, and who expect to do the same thing with btrfs, this question is as you suggested, certain to BECOME a FAQ. So adding it "somewhere", with the most appropriate initial "somewhere" likely being the user documentation section FAQ on the wiki, is indeed a good idea. But it's a wiki and as such the expectation is that users themselves do the editing. Go right ahead. Chris Mason's authoritative explanation's a great start. =:^) OTOH if you're like me you're more comfortable on the list, and editing the wiki is a big hassle. The information will probably get there eventually either way, but if you do it you make sure it's done /now/, not whenever someone else gets to it. So if you are comfortable updating the wiki, by all means do so, but if not, well, I've never done so either, so... -- Duncan - List replies preferred. No HTML msgs.
