Ok, but if making it layered (several "layers" or passes). To explain
my thought about how they should be sorted:
Layer 1 would calculate real dependencies of packages -- using current
use flags. Those dependencies would also be saved into portage tree
after calculating (--newuse would update them).
Layer 2 would be used to make a list of all packages, which would be
installed right now -- this happens when some emerge or pretend is
being done.
Layer 3 would only use those calculated dependencies and
ready-selected list of packages and sort them.
One possible sort would look like that:
* Packages, which have given importance, will have this importance
forever -- it will be written to world.
* When sorting packages, only those, which are directly in world, will
be considered -- dependancies are installed as late as possible.
It should be enough:
1. Make list
2. Add all packages, starting with those, which have higher priority
3. Add their dependencies, trying to put any of them right before the
first package, which needs them (more advanced sorting would use also
default priorities of dependancies -- putting them before first
package, which needs them, and after last package, which has bigger
importance than this first package)
Any other sort optimizations would be unnessecary as user can just use
right priority numbers to get everything ok with this type of sorting.
Sorting is good especially when user makes a long list of packages and
then starts to emerge them at once.
In my case i did install gentoo only at daytime, having my computer
off at nights (as i dont like it's sound in my room when i sleep). It
took several days -- and i started to use it right after getting it
up; i started also using kde right after it included kicker, konqueror
and konsole. I wanted to install graphics, toys and other such things
as last thing. And i didnt want to make pauses between emerges, but
had, because i wasnt always there, when one emerge was finished (as
they took hours).
