[gentoo-user] Kernel upgrade from 5.4 to 5.10: oldconfig "Restart config..."

[gentoo-user] Kernel upgrade from 5.4 to 5.10: oldconfig "Restart config..."

[Alarig Le Lay]

Hello,

Has the 5.10 LTS has been stablised, I tried to upgrade it on some of my
boxes, but `make oldconfig` doesn’t want to use my old config:
Here is my make output: https://paste.swordarmor.fr/raw/2rRh
And here is my config:  https://paste.swordarmor.fr/raw/YHaG

Does anyone else has to redo its configuration, and did you manage to
reuse the old one?

Thanks,
--

The 'make oldconfig' script steps through the previous configuration 
selections and stops at any new options which require your input.  In the 
pasted output you provided the first option asking for your input is your 
preferred compression algorithm for the kernel image.  Choose any one of the 
list below, or leave it to default (gzip):

Kernel compression mode
> 1. Gzip (KERNEL_GZIP)
  2. Bzip2 (KERNEL_BZIP2)
  3. LZMA (KERNEL_LZMA)
  4. XZ (KERNEL_XZ)
  5. LZO (KERNEL_LZO)
  6. LZ4 (KERNEL_LZ4)
  7. ZSTD (KERNEL_ZSTD) (NEW)
choice[1-7?]: 

Then proceed to the next kernel option and so on.

I'm always using  "make olddefconfig"  rather than  "make oldconfig" and
had no problems upgrading to 5.10.   After running "make olddefconfig" I
use "diff" to compare the new configuration  to a backup copy of the old
one,  and should something  catch my eye  I'm correcting it  using "make
menuconfig" as usual.

Sincerely,
  Rainer

Ah yes indeed, I never had a choice that early in the process. Thus, I
never saw the "Restart config..." and I misunderstood it. Thanks :D

It seems to be a nice upgrade process, thanks!

For the uninitiated, the difference here is that olddefconfig will
accept the default configuration value for any new/changed options,
whereas oldconfig will prompt the user for input.

The former is great if you just don't care and want to accept the
default, but it isn't right for every user.

fwiw, I think I've always just copied the old .config across, then done 
"make menuconfig". I think that also just accepts defaults for anything new.

It doesn't, it prompts for every change, with the default preselected.
It's more time consuming than running make olddefconfig but it does give
you the chance to see what the new options are, and read the help if you
need more.

Eh? Did you read 'oldconfig' where 'menuconfig' was written?
