| Or an alias, but what I mean is if I am handling packages, it should log

| Done that, been there, with HP-UX and swinstall, but Debian has tools
| more like the expensive HP ones, which I haven't tried out yet for
| managing groups of computers under Debian.
|
| The HP tools let you schedule trial updates to ensure dependencies are
| okay, and you have enough disk space in each logical volume. So be
| interesting to see how Debian compares. So you can designate some of
| your HP workstations as "test" boxes, and then schedule a test upgrade
| to make sure the upgrade will work, before scheduling the genuine thing
| for when the development team are asleep (everyone always tests things
| on the developers systems in my experience - "developer" is a little
| known synonym of "guinea pig" - probably because they often bring fixes
| or workarounds with their bug reports).
|
| swinstall (and friends) were the best of such tools in the proprietary
| world I saw, this was all "enterpise quality" software back in the mid
| 90's. Sure none of it is terribly clever, and you can get 99% with cron
| and a few scripts, but in enterprise environments, putting your own
| scripts in for this sort of thing is hard work, not least because it is
| tough for the little guys to test. Ironically schools and universities
| would make an ideal test site for such software, as they face the same
| issues, but downtime tends to be less critical.
|
| Don't get me wrong, I think Debian is superb, just want to learn (or
| fix) specific aspects. It is interesting how slow progress in the
| proprietary Unix world is in comparison to free software. Although I
| note that Debian stable/testing turn over is very slow, and solid, given
| the tagrets they set themselves the results are definitely comparable to
| proprietary Unix system vendors.
|
| Although an interesting question is was Unix slow because it tried to be
| unified. GUI development seemed to die after every vendor went with
| HP-VUE (oops CDE). This battle between standardisation and diversity
| seems to be my theme for the month.
