hello gentoo people,

I have neglected my gentoo system for over two months, and update is a total mess.

I decided to reinstall gentoo, but i am afraid of this kernel...
is there a way to see what is enabled in current kernel, so I can enable them in my new installation?

I looked in /usr/src/linux, but I could not know what is what.

Thank you

You most likely can get config from your active kernel. AFAIR this option is enabled by default, so just go for
zcat /proc/config.gz
Dump the output to file and later save as /usr/src/linux/.config and build kernel with --oldconfig
Alternatively you can copy .config from your previous kernel sources directory.

Also, updating 2 months old installation is not so bad, in worst case emerge -aeuDN world should do the trick. Even if it takes ages to complete.

Code:
kishta grom #  zcat /proc/config.gz > myKernel
gzip: /proc/config.gz: No such file or directory
kishta grom #


for update, i have issue with:

kishta grom # eix-sync

I suggest you take a copy of /usr/src/linux/.config on your existing system.
To be honest you should be able to update a system which has 2 months worth of updates, but if you decide to do a fresh install then I suggest you copy the /etc tree from your existing install so you can copy config information back on to your new install rather than configure everything from scratch.
There are a few other files it's worth taking of a copy of as well, the world file means you will have a list of packages you installed.

@while true, there are a few places where the kernel config could be:
  • /proc/config.gz (if you enabled IKCONFIG and IKCONFIG_PROC in the kernel)
  • If you enabled IKCONFIG as a module, you need to "modprobe configs" to see /proc/config.gz
  • If you enabled IKCONFIG (not as module), but not IKCONFIG_PROC, you can still extract the config from the kernel image with /usr/src/linux/scripts/extract-ikconfig (I haven't tested this one)
  • /boot/config-*
  • /usr/src/linux/.config

afaik

zcat /proc/config.gz >> myKernel

Code:

ifconfig -a
