Sometimes it is better to COPY the Linux kernel (&includes) from a Live distro - effect: ZERO dmesg's about sr0 drive!

• Knoppix Linux distribution is good example. Compilation (Kbuild) is often (or very often?) waste of time - this, that switch – with SATA / PATA driver, .config-file IMO strange combinations — is time-waster. Linux should bring normality, NOT Windows-typed bugs (which one is hibernation spinning down HDD three times). [But actual Linux versions have THIS hiber-bug still – Torvalds IMO seems not concerned about it if this bug is... BY DESIGN. „Design = resign”.]. One problem [CD] you can resolve but other is, as far as I study code – algorithmic one. Knoppix launches even from GRUB (the ISO file placed somewhere...) and this technique should be recommended when dealing with new hardware (avoiding unnecessary compilations if they produce so many hardware - year after year....). Some DVD drive not lasted even about several months.
• Includes' have symlink – pointing to kernel includes (so important, without need to seach for ....-headers package)
• Kernel, now 5.10.10-64 seems a bit faster sometimes
• ZERO dmesg's about sr0 drive! No horkages, no CD driver speed limit
