[gentoo-user] emerge improvements... again

[Jerry McBride]

I'm getting ready to make a post on bugs.gentoo.org to ask for a couple of 
feature enhancements for portage's emerge routine. I thought I'd ask here 
first, to see how everyone feels about them and if there's too much negative 
response I'll just drop the idea.

Two new features I'd like to see added are;

1- In /etc/make.conf add a new key to FEATURES that would cause portage to 
cleanup the DISTDIR folder if everything emerges cleanly. Perhaps "CLEANDIST" 
or "DISTCLEAN" or something similar would suffice. I never, ever keep the 
source files after a successfully emerge session and it would be nice if 
portage would take care of the dirty work for me.... automatically. 

2- We have "emerge world" that covers everything already installed and "emerge 
sys" that covers all the system related stuff.... How about "emerge apps" 
that would ONLY cover things NOT in  "emerge sys"? Face it, it'd be nice.... 
Right now, I have to resort to extra steps to "emerge apps" and well... it'd 
be a nicer chore for portage to handle.

3- Make a list of hooks available to hackers, like myself. I know I can 
implement the above features, but the emerge source is huge and teasing out 
the details is proving more time consumeing than actually implementing new 
code. Perhaps in /etc/make.conf there could be config lines like, 
"EXECUTE_AFTER_OK_EMERGE" and we could fill in a path to our own cleanup 
scripts... Or maybe "EXECUTE_AFTER_BAD_EMERGE" in the same case as above, but 
after a bad emerge run, etc....


So, what do you guys/gals think?
