just to chime in on the movability: i successfully moved whole prefix installations to other directories, and they worked fine (hint: i used chpathtool to adjust paths) the only limitation is, that the path has to be the exact same length (or less long, but that one didn't work for me yet, but that could be fixable). of course this is not really convenient, but it should be possibly for you to create "/home/user/prefix-with-long-path1" and "/cluster/disk25/user/prefix-short" those would be exchangeable. Of course chpathtool is possibly still not perfect, and i observed the one or the other segfault with certain files (none of those lately though). However you're free to fix it ;) Cheers, Markus > > It seems I'm hoping for the best of both worlds, which I might not be > able to get (or, not without a lot of work, and I guess I should at > least gain much more Gentoo experience first). > > Dag Sverre >
