[gentoo-dev] Reverse-dependency support in Portage2 ?

[gentoo-dev] Reverse-dependency support in Portage2 ?

[Dan Naumov]

Hey.

I would like to know whether some kind of reverse-dependency support is
going to be included in Portage2. It would be nice if in case of
unmerging a package, Portage would let the user know whether some
installed packages need it and if so, what packages do.

Sincerely,

I would second that feature request.  It would also allow for some intelligent 
'auto-healing' of the system, by allowing one to (optionally) recompile any 
packages dependent on an ebuild that has just been upgraded so they run 
against the newest version or warning one before a package upon which others 
rely is removed.  This is the one feature I miss most about Source Mage 
(sorcerer).

Please note this is very easy todo by hand.  I wrote a script in an hour 
or so once that did reverse dependancy look up.  This was sometime ago, 
though, and I don't think the python-portage api is the same anymore. 
Is this true?  If I get a chance I'll look into it and post the script 
to the list.

Well frankly, wouldn't a second to a second be a third? Therefore I
hearby 'fourth' that measure. :)

Yes, that must be something that the next version of portage address.
I also second that feature request!
