You could have a post-install hook in /etc/portage/env/$CAT/$PKG for each
of the affected files, something like
post_pkg_postinst() {
rm -f /etc/._cfg_hosts
}
You'll need to check the syntax as it's a while since I've used this.

If that works and I were to use chattr +i it might be useful to make a list of what's now immuteable so later adjustments could be made when appropriate. -- Jude "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

My guess is gentoo includes the chattr utility. Does emerge respect chattr +i /etc/hosts? -- Jude "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

If no bugs have been introduced since the last time you used it, if the user has their eyes open and doesn't make a mistake. I do not know if it has an option to keep a copy somewhere safe, and again, I run multiple distros and like a solution that, for me, works on all distros. To each his own. ;-) (And shame on you for being 'a few months' behind on your updates) ;-)

It's not only about whether that option works today but whether it keeps working in the future, assuming it really works at all. There's also the case of the machine going down, a disk corrupting, etc. and how long it takes to find the notebook where supposedly we had the notes about how we set things up. And what about other machines using other distros? I'm only offering what I do. I personally wouldn't run the cron job but for all my machines part of my backups is a big list of config files kept elsewhere on the network so that I don't have to reconstruct that sort of config stuff. Add to Walter's list other things like NFS exports and for old people like me it's just easier to be prepared. Just my POV.

Re: [gentoo-user] Can some config files be automatically protected from etc-update?
Really, etc update has a facility for skipping whatever files you want.
