emerge --unsync

[danboston]

Did an "emerge --sync". Regretting it. I've not actually emerged nor unmerged anything since. Time to revert. The "emerge --unsync" is a handy command that lets one undo the effect of the last "emerge --sync".

To bad there is no such command ... or is there, but under a less-obvious moniker?

Thank you.

People ask for this somewhat often, but there is no such command. You could sync to an older mirror, if you found one (or kept one of your own) that was sufficiently out of date. If you have not emerged anything yet, then no damage has been done. Why do you regret this sync? How can we help you move forward?

[danboston]

Thank you for the replies.

p.s. The regret was caused by a huge long error message from an emerge world (before it started, so I was able to tell it to just please stop emerging this time) where apparently anything that used, was used by, or even slightly incorporated perl was a problem for emerge. thread here.

p.p.s. Just seemed an --unsync would be easier/faster than a restore of "/" from backup.

What you have to do is tar up /usr/portage before you sync, so you can restore it if you need to. This is especially true if, after syncing, a package you use has disappeared or the version you have decided to stay at has disappeared. . You can then restore it to /usr/local/portage if you have a local overlay there.

danboston,

You can't live in the past.
Do your --sync whenever you like but pick your time to deal with the update.

In those cases where you absolutely must stay in the past for some particular package, you would be much better off pinning it in a local overlay as soon as you decide you want not to upgrade, rather than waiting until the Gentoo developers move to remove it.

As Tony says, an archive of /usr/portage is sufficient to go back in time. A squashfs of a known-good tree is relatively space efficient (currently ~86M (almost double from a few years ago, if I recall correctly)) way to retain a historical tree.

There's a git repository, why not use it?

This is an interesting discussion. I'll write a script that'll do this for ya, buddy!

Ah, looks like Portage would need a presync.d hook in order for me to accomplish something...
