Thanks for the information. That is one are where I think Gentoo can
definitely improve. Making it so you can tell if removing a package
will kill anything. I would imagine this is probably not an easy task
though.

You can check whether the package you intend to remove is a dependency
of another package ;-) You can do it with "equery depends <package>".
Cheers,

I like the old 'etcat'. You can still find it on your system at
/usr/share/doc/gentoolkit-<version>/deprecated/etcat/etcat.
I use 'etcat versions <pkg>' all the time. The number in parentheses is
the slot that package is in. E.G. for php:
[ Results for search key : php ]
[ Candidate applications found : 13 ]
Only printing found installed programs.
* dev-lang/php :
[ ~ ] 4.3.11-r4 (4)
[ ~ ] 4.4.0-r4 (4)
[ I] 4.4.1-r2 (4)
[M~ ] 5.0.4-r4 (5)
[M~ ] 5.0.5-r4 (5)
* dev-php/php :
[ ] 4.3.11 (0)
[ ] 4.3.11-r1 (0)
[ ] 4.3.11-r3 (0)
[ ] 4.3.11-r4 (0)
[ ] 4.4.0 (0)
[ ] 4.4.0-r1 (0)
[ ] 4.4.0-r3 (0)
[ ] 4.4.0-r4 (0)
This shows that I have ver 4.4.1-r2 installed on my system in slot 4.
I haven't found an equivalent w/ equery. I create a symbolic link from
the etcat location above to /usr/local/bin. However, everytime
gentoolkit is updated, I have to update the link.
Cheers,
Kevin

maybe there should be some options when updating and emerge tries to bring
in new slot, see, now i have qt3 and qt4, qt3 was emerged as kde dependence
but nothing depends on qt4. so there waste of time and space unless i don't
need qt4 for development or whatever. am i right?
