[gentoo-user] Stop and continue emerge -e world

[Petr Uzel]

Hello everybody!
I'm currently running emerge -e world because of gcc upgrade. I would 
appreciate if I can stop this emerge and continue tomorrow from where it was 
stopped.

I have two questions:

1) Is there any possibility to stop and later continue (after reboot) emerge 
-e world without compiling every package again?

2) If I do this, will be the system usable after reboot? (some of packages 
compiled with gcc-3.3.6 and other with gcc-3.4.5)

Thank you, Petr

OK, I can answer this myself (I hope correctly) : "pick your emerge" script or 
emerge --resume. I should better RTFM.

wouldnt say it is possible, unless u have hibernaton enabled, which
probably is not in your case. besides emerge --resume only resumes not
downloaded fully files from internet to be downloaded...

Not so. emerge --resume restarts the previous emerge process, even after
a reboot, exactly as Petr needs.

I doubt the fact that some packages are compiled with one GCC and others
with a different one is going to cause a problem, especially as you'll
carry on with the recompiling after the reboot. Even if you don't reboot,
your system will be running with a mixture of 3.3/3.4-compiled packages
during the emerge.

Ok, I'll give it a try. Thank you for quick answers.

That should not be a problem.  Before I switched to Gentoo I used
Ubuntu.  Ubuntu compiled the kernel with a different version of gcc
than what most of the other programs were compiled with.

Actually, the faster way would be to use revdep-rebuild instead of
emerge -e world (isn't this mensioned in the upgrade guide for gcc?). If
you still have gcc-3.3.6 installed on your system, you won't have a
problem from rebooting (as far as I know).

Just a note when you issue an emerge --resume, if you stopped the
emerge in the middle of a compile it will not pick up in the middle it
will start compiling that package from the beginning again.

I have a slower computer (celeron 800 mhz) and a family that doesnt
like to leave the computer on all the time so when I ran my gcc
upgrade it took close to a week and I didnt encounter any problems
during this time with a system that was only partially recompiled with
GCC 3.4.

what i meant is that it will have to recompile allover again(it might
use some cahching  mechanizm as well?) if he has turned "emerge" process
off and in case if file wasnt downloaded fully it(emerge) will resume
file downloading

Yes, it is. But in addition to upgrade of gcc I have changed CFLAGS form O2 to 
O3 so I wanted to recompile the whole system.

No it won't, it will start again with the package it was working on when
the emerge was interrupted.

I've found that in situations like this, it's useful to have
FEATURES="keepwork" in /etc/make.conf, provided that you remember to
delete the contents of /var/tmp/portage every now and then...

Is it possible somehow to use a feature like "keepwork" that
deltes /var/tmp/portage after a successful emerge, but not after an
interrupt? (Which is how I assume it works now?)
