Re: [gentoo-dev] Re: Unmerging dependent packages

[Corvus Corax]

If i got right what has been requested, i can only say I'd like to have such a tool, too :-)

Imagine some small but widely used library that usually gets linked statically and so is used only at build time.

lets say we call it "zlib" ;)

lets further assume, some geek finds a security leak in it, which allows execution of arbitrary code, which leads to any
software using the library beng exploitable, also theres a new version out there soon, which is fixed, as always ;-)

if i had a server running, and an exploit already "in the wild" i'd rather like to upgrade not only this library itself, but also each and every package that
used it for building.

so a emerge option that searches for packages that depend on package XY would be cool, especially with optional turnable recursiveness.
for example "--flush" and "--deepflush"

so i could do "emerge --deepflush zlib"

or if i have a system which is going to be stripped of its graphic card and i dont need x-applications anymore i could do
emerge X --deepflush unmerge

it could also be usefull, when turning on a useflag that was turned of until that time, for example:
USE="alsa" emerge --flush alsa
to re-merge all packages that would have optional alsa support and such depend on alsa in case of alsa useflag being set :-)

I think that would be usefull, whadda you think?
