Description Andy Kriger 2004-04-18 10:12:49 UTC
It is possible using etc-update for a user to destroy their configuration. As a newbie, I did not realize that etc-update using -5 would overwrite EVERY file in /etc (not just those that had changed in the last emerge). I would suggest the following enhancements to etc-update...
1) More verbose explanation of what each option does ('mv -i' is not enough)
2) Automatic backup of /etc before doing a catastrophic change

Reproducible: Always
Steps to Reproduce:
after an emerge that changes etc files, run etc-update with the -5 option

Actual Results:  
all etc files were overwritten

Expected Results:  
only the etc files that had changed in the previous emerge should have been

I have seen a number of posts in the gentoo msg boards dealing with similar
problems using etc-update. That would seem to indicate a problem with the tool
and  not the users. Sometimes it is simple newness to Linux (not realizing that
the /etc directory needs to be backed up frequently) or not reading the
instructions fully. However, it seems that etc-update can be improved to
eliminate these problems in the future.

how did you even find out about the -5 option? i checked the man page for etc-update and it doesn't mention args.  --help also doesn't do anything for me.

The -5 option is mentioned in the etc-update instructions. After etc-update gives you a list of files that need updating, you have a prompt instructing you to enter the number of the file you want to update. The instructions for the prompt mention other options (-1, -3, -5) with brief explanations. From my reading of it (admittedly quick), -5 looked like it would update the files in the list (not all the files in etc) w/o prompting me for each one.

Putting a hold on feature requests for portage as they are drowning out the 
bugs. Most of these features should be available in the next major version of 
portage. But for the time being, they are just drowning out the major bugs and 
delaying the next version's progress. 
Any bugs that contain patches and any bugs for etc-update or dispatch-conf can 
be reopened. Sorry, I'm just not good enough with bugzilla. ;)

1) is obsolete by now I think
2) see comment #3 (plus about a dozen other alternatives
