When running through the ._cfg0000 files that portage dumps around, I find that many of them differ just by the header line managed by source control. If portage could note that "oh, this file has only changed the header line" and procede to place the new config on top of the old. Something like: head -1 $current_cfg > tmpfile1 head -1 $new_cfg > tmpfile2 echo "<" > tmpfile3 cat tmpfile1 >> tmpfile3 echo ">" >> tmpfile3 cat tmpfile2 >> tmpfile3 diff $current_cfg $new_cfg > tmpfile4 if [ "`diff tmpfile3 tmpfile4`" == "" ]; then mv $new_cfg $current_cfg else mv $new_cfg `basename $current_cfg`/._cfg0000_${current_cfg} fi Note: logic is just typed in, not tested, at all. Note2: this might be a duplicate. I couldn't find one though. Jason
/etc/etc-update.conf # Whether trivial/comment changes should be automerged eu_automerge="yes" quite good enough ?
Inactive, but the problem was solved.
