How does that all map to multiple users/groups? How does that map to USE-conditional users/groups? How does that map to users/groups shared between multiple packages? Besides, this sounds a lot like games.eclass... will developers be required to patch upstream software now to force support for using custom users/groups? > What happens if the ebuild wants to create multiple users/group? > Currently, I want to ignore that case and focus on the 80% ebuilds that > can profit from such an eclass. Do you have specific numbers? I don't see 80% of ebuilds caring about users/groups. I don't see the problem you are trying to fix. Is it one of those problems that someone thinks it's awesome to make everything declaratory, and add tons of middleware to make the declaratory work somehow for the most common use cases? -- Best regards, Michał Górny <http://dev.gentoo.org/~mgorny/>
