[gentoo-user] Using Gentoo as server and desktop

Hi mates,

I would love using Gentoo as Desktop and Server OS. I used sometime ago, but it caused me the fact of not being able to upgrade my systems weekly or daily, because sometimes you needed to upgrade the kernel and I was not really sure that the config entered for the kernel (loaded through Genkernel but with menuconfig and there load .config file) that was written with previous kernel version building was going to not cause something weird or bad functioning of newer built kernels with that config.

Does exist a way... where you could emerge world, update all the system, finally end up by upgrading the kernel and being sure that the old .config you used through menuconfig (or by any other way of importing) would not select erroneous parameters in newer kernels?. I though there were some... lint options for the .cofig?. I think I have used them sometime ago....

So for sumarizing, how do you manage for keep your systems up-to-date using Gentoo?. How do you manage to keep your kernel upgraded?.

Cheers,

I use the distribution kernels, gentoo-kernel or gentoo-kernel-bin as
appropriate.  I didn't see the upside in trying to micro-optimize my
kernel configuration and builds just to save some memory/disk space.  I
have far more of both of those than I do unoccupied time.

Thanks a Lot for your contribution Matt!

All my systems run custom-configured kernels built from on stable
gentoo-sources.

All I've ever done for a kernel upgrades is to go into the new kernel
source dir and do the following:

# zcat /proc/zconfig >.config
# make oldconfig
# make
# make install

For the past 20+ years, that has always worked fine for minor version
changes (e.g. 5.15.x ⇒ 5.15.y)

There have been a few major upgrades in the past 20 years when a large
kernel subsystem change required some sort of manual intervention with
a "make menuconfig". But, I can't actually remember the last time it
happened (it's been years).

Also, don't forget 'make modules_install' for any modules not built in the 
kernel.

In my case genkernel will handle it but yes 👍😀

Good catch. I forgot to mention that. It's always the step after "make
install".  Every once in a while I do forget to do that step. For my
systems that usually means that X won't start until I do the "make
modules_install".

You can actually combine the two with
make install modules_install
:)

It may even be possible to do something like
make bzImage modules install modules_install
(I use sources from kernel.org and those four actions are what I use 
regularly, though in two separate make runs).

Thanks a Lot Grant!!

Nice to know you never suffered issues…

I would to this way with config but, later genkerneled and loaded through menuconfig the file…

I prefer genkernel Because provides flexibility but creates you an initramfs for returning from sleep/hibernate… although I later change slightly that initramfs lol 🤣

The only way you will make it work, is if you have a minimum one working
backup.
You upgrade a backup first, check if everything is working correctly then
you update the main system.
Have been doing it for over 20-years.

It is not only the kernel that you have to worry about.
