Got that from one of the zillions of howtos ...

I see the point in this. (AFAIK there is no way to break up "emerge -e xy" into smaller pieces, something to do in several separated steps. >>From your posting I conclude that it also won't do any harm to re-emerge selected parts with new CFLAGS?) So does it make *any* sense to re-emerge stuff like OO.org or Thunderbird? Maybe I will let my small distcc-cluster work on this ... what else should it do? :-) Apart from this I have enough computer-related experience to know that I simply should be happy with the luks-encrypted/cpufreq'ed/hibernating/etc. gentoo-system I now have at hand, instead of spending numerous hours to gain minimal speedups. And I am. Thanks a lot, Stefan. -- gentoo-user@gentoo.org mailing list
