One thing that was going to get on my nerves is now fixed in 0.044:

Changelog wrote:
- Do not record states in postsync when state is identical to the latest recorded state.


No more redundancy when auto-recording after --sync. --- Eh. You don't know about this feature?

demerge-ebuild wrote:
/etc/portage/postsync.d/demerge-record has been installed for convenience
If you wish for it to be automatically run at the end of every --sync simply chmod +x /etc/portage/postsync.d/demerge-record
If ever you find this to be an inconvenience simply chmod -x /etc/portage/postsync.d/demerge-record


Enjoy! :)

Sorry, that I bring back this dusty thread, but I just found this tool after another system breakage due to updates (no more hibernate, stop media key tunes down volume, system sometimes hangs on starting X) and had no easy way to revert to the previous state.
First I thought I would have to write something myself. Try to emerge to a temporary file system, record files that would be overwritten and create a backup from that. Demerge is a great alternative, thank you!

Aha! I was wracking my brain to try and remember what this util was called. I'm currently experimenting with different DE's and this tool is friggin' essential for rolling back without having to manually record and unmerge the 100+ packages that a DE normally tries to pull in.

Thank you so much for making this; It is probably the single most useful Portage tool. IMHO it should be a standard part of Portage!

Just a tiny little suggestion:
Code:
emerge --depclean
...will unmerge all the no longer needed dependencies.

Yeah, I knowabout depclean, but from past experience I'm wary of it - a) You still need to record the originating packages, which aren't necessarily the ones you named, and b) Last time I used it on something with such complex dependency chains, it broke the system horribly...

demerge just *works* :D
