Having looked at a few I thought existed, I can see that over time the manual has improved a great deal in this respect. In fact, I'm not a regular reader of the manual (I read it in the 1990's) and a skim through just now proved that a lot of good work has been done by you guys! (These days I read man pages). The port upgrading is one section of the manual I do keep going back to, and I've wondered about the different options for some time. On a quick glance: 4.9 Shells - "it's a matter of taste". Factually correct but not that helpful in isolation (i.e. if you're new to it and have no taste). I'd say "Use /bin/sh" as a default because it's the most standard (for running scripts and across different platforms) and guaranteed to be there on the root partition. I'm aware that discussion on the merits of different shells tends to spark a holy war on the subject. It might be helpful to point out that you can run one shell for another (I log in using /bin/sh but switch to csh most of the time). 4.10 Text Editors - possibly worth pointing out that 'vi' is the standard. I tell students they might as well learn it because they won't be able to avoid it forever (vipw &c). Eight Megabytes And Constantly Swapping doesn't raise the smile it used to. As to the strategies for disk mirroring, there's been more than one listed in the past. I got gmirror working, and stuck with it, but what's vinum and should I care? Now there's ZFS too, but I think they're mutually exclusive. And then there's HAST. And didn't someone say that UFS was obsolete? Or was that vinum. And how exactly do I read ext3 - I got it working eventually, once. (Incidentally, I do know what vinum IS but the only reason I've ever looked at it was for mirroring - it might be a better way to go but nothing in the manual spelled it out). But I don't want to sound like I'm moaning on. I've actually bought half a dozen new HP Microservers , specifically to experiment with ZFS, HAST and all this new file stuff. Naturally, I also plan to write up the results. Regards, Frank.
