Mind you, on this i5 box it takes under five hours each time to remerge the 980 packages, including Libre Office. Two packages didn't compile: lame (wrong file size; I'll try again tomorrow) and kmymoney (compiled fine when called on its own, not during -e world). To get things compiling I removed all signs of graphite. I'm not sure whether it's worth the trouble of putting it back in again. Thoughts, anyone? -- Rgds Peter Linux Counter 5290, 1994-04-23

On the one hand, it's kind of fun and educational to have something break in a novel way so that you can figure out how to fix it. On the other hand, those things only break when you have something important to do. I try to keep my laptop in good shape, and then do the unspeakable to my desktop machine at home. If I ever need to do something urgently (fill out a spreadsheet to apply for a scholarship) and something is broken (libreoffice can't find libhahakissyournightgoodbye.so.1) I can always walk into the living room and do it on the laptop.

Only snag, in my case, is that with passing years I'm beginning to find myself going round in circles, gnashing my teeth more loudly each time. On the other hand, those things only break when you have something important to do. Now that's just paranoia! You only remember the breakages that coincide with inconvenience.

My unspeakable things aren't open to discussion in this forum :-) But I do have an 8-year-old dual-Opteron box that I can do indescribable things to at whim. It still shows many a younger system a clean pair of heels but it is rather too noisy for everyday use, not to mention overnight. -- Rgds Peter Linux Counter 5290, 1994-04-23
