[for just one swipe going to fbsd-fs too] In article <199611110210.SAA01988@root.com>, dg@root.com wrote: : >I'll have to defer this to someone more knowledgable about the : >internals of FreeBSD... : : We didn't have async support in 2.1.0. We had partial support for it in : 2.1.5, and full support for it in 2.2/-current. In -current, it should take : only a few seconds to delete /usr/src. :-) (I haven't tried, however) The Ahh excellent I guess it's time to grab some code and start following freebsd-current. Thanks! : ultra-fast async in 2.2/-current also means that it has a much higher chance : of trashing your filesystem if the system should go down before the stuff : is written out...so it's a mixed bag. Well if we lose the newsspool, overviews, and history it's not such a big deal, just wait 6 days and it's all back again. In some ways it's a Good Thing as all the smut and spam are gone, albeit temporarily. Note our users would not agree with this. Of course 99% probably wouldn't notice if I dropped everything other than alt.binaries.pictures.erotica, but that's another story. Would be neat to have a new class of filesystem, call it "expfs" (expendable filesystem) for low-value high-volume stuff like news articles. Could have default async writes, noatime, preferred time optimization, anything else that would lend itself to this sort of thing. Regarding current, can one do a surgical strike (make on kernel only) install on it or is a make world needed as it would be for the NOATIME patch? -- Howard Goldstein <hgoldste@bbs.mpcs.com>
