Mostly a general linux question, but where it needs to be specific I am referencing Debian 12 Bookworm amd64 UEFI booting through grub(not direct kernel stub).I have secure boot disabled in firmware for some multiboot reasons and I have options for signed or unsigned kernels.
- Are there any negative impacts of a signed kernel, possible incompatibilities or failures to load modules?
- The signed kernel is about 2% larger which is insignificant for my system.Do use the same modules or require separate special builds?
- Can I have a signed and and an unsigned one the system at the same time, similar to having an older stable and very new kernel of the same series, or regular and real-time kernels?
