resuming a emerge --emptytree system

[slowpoke]

I'm doing a new, first time, install of gentoo, and (after getting around some downloading problems) I was able to prefetch all the packages and ran

Code: Select all

emerge --emptytree system

I ran into an error that said i needed automake installed, and it stopped. This was a couple hours into the compile. I then guessed and ran emerge automake, and it seems to have installed the package. I'm wondering if there is a way to contiunue the compilations where I left off with the emerge --emptytree system. I would really liketo avoid going through allt he compiling that it's already done

since u emerge sthg else between the error and now, it's no more possible, else you 'd just have to

Code: Select all

emerge --resume

Also for emerge --emptytree world if you need to do it one day, you can do this emerge -e world || until emerge --resume --skipfirst; do date; done

[slowpoke]

Code: Select all

emerge -e world || until emerge --resume --skipfirst; do date; done

I'm a new to this, so does this try to do an emerge -e, and if it fails it skips the first one and resumes?

Also, is there a way of knowing which packages did not get installed if I do do that?

Thanks for the help

emerge -e world || until emerge --resume --skipfirst; do date; done

what does the "do date" do?? thanks...

do an emerge -e, and if it fails it skips the first one and resumes

yep (hu, the first one is the one which just failed)


I had the same question a few days ago;;)

hihi, all the links given, and given by other links were really interesting. Hope u'lfind what you want

OK, since the OP seems to have emerged autoconf right after the emerge -e system failure, this will not be helpful to him. But in case anyone else with similar compile failures looks here and they have not emerged autoconf yet, this advice will save them a lot of time.

1. Copy /var/cache/edb/mtimedb to a safe location. I prefer root's home directory for this.

   Code: Select all

   cp /var/cache/edb/mtimedb ~

2. Emerge whatever package is needed. For example, those compile failures caused by "missing automake" will require emerge automake
3. If the emerge missing-package-name completes safely without errors, move the backup copy of mtimedb back into position and overwrite the mtimedb that is already there.

   Code: Select all

   mv ~/mtimedb /var/cache/edb

Hope this will help someone save lots of time. It did for me.

I just discovered this trick on my own (by reading the 'emerge' source code), and I must say - this is a HUGE help. I hate getting into the middle of a huge long emerge (like emerge -eD world) only to have it fail requiring the installation of another package. Any attempt to install that required package would whack my original attempt, forcing me all the way back to the beginning & wasting a lot of time.

MODERATORS: This trick deserves to be in the hall of fame - best little life saver I've found yet.

emerge -e world || until emerge --resume --skipfirst; do date; done

what does the "do date" do?? thanks...

date displays the date.

The "do" is part of the "until" syntax.

until [condition] ; do [commands] ; done

This means "until [condition] is met do [commands]."

I tell you - the Gentoo devs may hate me for it, but I am slinging mtimedb files left and right! If I had any bandwidth to pick up python & portage right now, I'd be writing an app to preserve snapshots. Seriously - I've never been more excited about a portage hack since qpkg.
