When I first started using Gentoo, I didn't know what etc-update was for but
each time I emerged a package it would complain about all the ._xxxxxx
files. Upon further investigation I realized that I really wanted some of
the updates and I didn't want others. I wrote a little shell script that
finds the files, does a diff against the original and gives me a simple
prompt: Update, Ignore, Remove new:
A simple enter key, or a U or u will just install the new file.
I lets me ignore the file this time and R removes the new version.
R removes the new config file. This is especially handy if it would wipe
out my /etc/fstab. There are few config file changes that I need merge in
by hand.
I have seen other similar scripts, and I have tried etc-update, but I keep
using mine. I have cleaned it up a bit and it is attached.
Cheers,
