Re: [gentoo-portage-dev] Undo feature in portage-ng ?

[Hasan Khalil]

I am going to begin work (soon) on implementing a system to monitor a 
given directory for file changes, additions, etc. and perform a 
user-defined action on the added/changed/etc file immediately. This 
system could theoretically be used in conjunction with a local CVS 
repository (a CVS mirror of /etc, for example) to provide the 
functionality you are looking for, I think. More details can be made 
available by request either to the list or on a per-person basis; 
whatever you guys (and girls) want.

Aside from that, if the official portage dev team wants to include 
something like this backup system in future releases of portage (or 
portage-ng), I'm willing to take a shot at solving this problem. In the 
last few minutes several thoughts have already come to mind on how to 
solve this, but I'm still not sure if it's really desirable as a 
capability of emerge. Let me know, and I'll begin serious brainstorming.
