You can run this before running etc-update to save yourself some work.
NB.
1. This needs gentoolkit to work
2. You need to do this before the old package that installed the config file is cleaned (either through an emerge clean or autoclean)
3. Please make sure that copy/cut-and-paste to the script text file does not remove spaces or modify line-ends.
Code: Select all
#!/bin/bash
# This script checks config files in directories with config files and
# checks whether their checksum matches known checksums in /var/db.
# If a checksum matches, the file has not been modified since the emerge
# and can be overwritten safely. These files are presented and queried
# for update individually or in one shot
#
# You can run this prior to running etc-update to save some work in updating
# files that you have not touched
