Yes, besides /var/lib/portage/world and /etc/ you may al= so want to back up
your /boot and kernel config, assuming the hardware = (MoBo & peripherals) is the
same (same drivers)=2E I wouldn't both= er backing up portage, a resync will
download it afresh=2E You might w= ant to save /distfiles if you're on a slow
Internet link, but it has to= be a copy of the current versions, otherwise the
latest version of eac= h package source will have to be downloaded anyway=2E

If you're run= ning databases you'll also want to keep a backup of the
respective /var= /lib/*sql directory and if you're running a webserver /var/www/
* - but= you would be aware of the need to keep a fresh backup of all this data
= anyway=2E

Also good point, one can always do a "make o= ldconfig" on a new kernel
to recover specific tweaks=2E

Regarding= backing up the portage tree, the binary packages won't do
much if the l= ast sync is, say, one or two months old or even worse if
older=2E To use= "emerge -K" one must have the same package version built
in the binary = package as the one present in portage=2E That's what I'm
facing right no= w, it seems my binary packages won't be so helpful
after all - I'm begin= ning to think I'll have to go back to stage-3=2E=2E=2E
