Over at:

https://github.com/vyos/vyos-build/blob/rolling/scripts/package-build/linux-kernel/config/x86/vyos_defconfig

1. Header should be updated to reflect for which kernel version the config is made from.

Currently it says 6.6.93 but clearly Stream 2026.03 use kernel 6.6.128 and latest rolling use newer than that.

2. Several variables are currently missing.

These are seen in latest stream or rolling ISO so suggesting to include the output of these and replace the current one.

For example a full config from latest stream is available at:

/boot/config-6.6.128-vyos

But a better choice would be to use similar from the latest rolling instead.

Having the kernel config being up2date with actual content is not only formally correct but would make life easier for troubleshooting to be able to see what are the current settings are directly in the repository rather than having to first install a specific version and find out through /boot/config-*.
