upgrading debian-sources requires 14 GB in /var/tmp

[hick518]

When I installed Funtoo, debian-sources was included as a binary and did not need to be compiled.  Now there is an upgrade available, and 'emerge -pv debian-sources' shows USE="binary".  I assume that means I will get a binary kernel that does not need to be compiled (please correct me if I'm wrong).  But when I try to do the upgrade, emerge fails with:

 

"There is NOT at least 14 GiB disk space at "/var/tmp/portage/sys-kernel/debian-sources-4.4.6/temp". 

 

That is a true statement, but I am wondering why I need that much space to install a binary kernel.  Is that a bug in the ebuild?

Cardinal, thanks for all the info. I still have a lot to learn.

 

For now, I have decided the easiest thing for me is to stick w/ debian-sources and do this:

 

mkdir /home/tmp

PORTAGE_TMPDIR=/home/tmp emerge -av debian-sources

 

It's currently compiling.

The debian-sources ebuilds specifically check for 14G free space if binary use flag is enabled.

drobbins knows from personal experience that is a free space requirement.

I installed linux-debian-sources-3.16.7 which was in testing back in May 2015

rj@funtoo ~ $ du -sh /usr/src/linux-debian-sources-3.16.7/
8.8G    /usr/src/linux-debian-sources-3.16.7/

Install started at 2.2G with binary use disabled, compiling kernel adds another 6.6G

gentoo-sources is much lighter @ 1.1G

rj@funtoo ~ $ du -sh /usr/src/linux-4.4.1-gentoo/
1.1G    /usr/src/linux-4.4.1-gentoo/

Install starts at 592MB, kernel compile adds another 508MB.

Whats added depends on configuration, gentoo-sources is slimmed down to the minimum with no initramfs.

Debian-sources I  used config-extract and added a few items so it's heavy on modules. 

I package.mask debian-sources and gentoo-sources > version installed.

I don't want to be bothered to update kernel every time a new version comes along.

My hardware is old, upgrading kernel does nothing for my user experience.

I guess I misunderstood what the USE=binary flag means. 

 

Is there a way to get a pre-compiled kernel using emerge?

[cardinal]

Pre-compiled kernel and initramfs is only included in stage3.

Future kernel updates on post install funtoo require building the kernel.

The kernel and initramfs build is automated if linux-debian-sources is merged with binary use enabled and you have 14G free space.

Since you don't have enough space use gentoo-sources with genkernel to update kernel.

Genkernel has a generic kernel configuration:

genkernel  all

There is no free space check.

I think you should try to compile your own kernel instead, hick518, It will finish in a few minutes instead of a couple of hours.

 

With

lspci -v | grep Kernel

you will see the name of the most important drivers, it's really easy.

I successfully compiled my own kernel using:

 

emerge gentoo-sources

genkernel --menuconfig all

 

It was quite fast compared to compiling debian-sources.  Thanks for the tips, guys.

 

I did have a small problem with genkernel, which I described here:  http://forums.funtoo.org/topic/938-missing-devrtc-in-genkernel-of-gentoo-sources-446/
