Case in point: my FreeBSD 6.2-RELEASE installation on a 233 MHz PII (one of those Slot 1 processors) with 128 MB of RAM runs just fine and serves well the purpose of 24x7 downloading and serving FTP; home scale, of course. Attempts to live boot Plan 9 on the same machine fail because some 9wacko believes CD-ROM drives must be secondary master or something--and I won't move a jumper to suit a 9wacko's whim; not that I've ever been asked to do that. --On Monday, November 03, 2008 5:23 PM -0800 Lyndon Nerenberg wrote: >> A thought ... >> >> Shared libraries do 2 possibly useful things: >> 1) save space >> 2) stop you having to re-link when a new library is released. >> >> Now 2) doesn't really happen anyway, due to .so versioning hell, >> so we're left with 1) ... > > I can run Plan 9 quite nicely in 128 MB of RAM.
