Linux kernel options not set

Post by flexoron » Mon Feb 25, 2019 10:54

Hello

Upgrade reports kernel options not set.

Repository: sabayonlinux.org
Revision: 3936
Kernel: 4.20.12

## Unpacking: app-emulation:docker-18.09.2.9244d1b96a9a563af5f6531f96d2d70a7fbda8d0~0.tbz2
* Checking for suitable kernel configuration options...
* CONFIG_AUFS_FS: is required to be set if and only if aufs-sources are used instead of aufs4/aufs3
* CONFIG_AUFS_FS: is required to be set if and only if aufs-sources are used instead of aufs4/aufs3

How to check this requirement? There is no option CONFIG_AUFS_FS in /usr/src/linux/.config

## Unpacking: sys-apps:systemd-239-r4.892c2bebf4a519cc7130776cc419844efd0e5d23~0.tbz2
* Found sources for kernel version:
* 4.20.0-sabayon
* Checking for suitable kernel configuration options...
* CONFIG_CHECKPOINT_RESTORE: is not set when it should be.
* Please check to make sure these options are set correctly.
* Failure to do so may cause unexpected problems.

/usr/src/linux/.config:
# CONFIG_CHECKPOINT_RESTORE is not set

It might be necessary retouching the kernel build?

In my Sabayon installations, i have two, the new kernel is working. I carried outo the upgrade of the kernel in this manner:

1. Open Sabayon.... then open a terminal:

Code: Select all

# equo up
# equo u -av
This upgraded all my Sabayon, then i changed the kernel with kernel switcher:

Code: Select all

# kernel-switcher list
# kernel-switcher switch sys-kernel/linux-sabayon-4.20.12
# systemctl reboot
All is working fine!

This applies to Docker and the question is how to check whether aufs4/aufs3 is in use. It doesn't affect the system.
* CONFIG_AUFS_FS: is required to be set if and only if aufs-sources are used instead of aufs4/aufs3

This might be critical because Systemd is a pawn in the game(known as number one, /sbin/init, pid 1).
* CONFIG_CHECKPOINT_RESTORE: is not set when it should be.
* Please check to make sure these options are set correctly.
* Failure to do so may cause unexpected problems.
