[gentoo-portage-dev] Suggestion: Backup option in make.conf

[Rafael Fernández López]

Hi,

My suggestion for portage is: when you do an "emerge -vuD world", you have
to work at the end of the emerging with the /etc config files and see the
differences to know if you want to overwrite file by file or not.

Well, what I want is to have a backup of all them (one backup, and only
one). For that goal, it can be used a new option in make.conf like
"backup_etc_files=yes" if you want to turn this on.

By turning this on, an "emerge -vuD world" can be done in one shot, I mean,
you can do an emerge -vuD world, and all the files could be replaced
(overwrited) by the new ones (etc-update), but you'll be able to access to
your backups if anything is wrong, so you don't have to go file by file
looking at the differences between them.

I suggest to name them "whatever.conf" (our original file) ==> "
whatever.conf.backup" (our backuped file)

Thanks,
Rafael Fernández López.
