testing/dracut: integration into alpine
I'm currently testing dracut to see what other issues there are to figure out before it's moved to community
- Microcode embedding requires cpio with --file flag: https://github.com/dracutdevs/dracut/blob/8410ee22903403cd673a22692a084125c835cbe9/dracut.sh#L2293
- grub-mkconfig (/etc/grub.d/10_linux and similar) doesn't recognize /boot/dracut-* entries for boot entry generation (related more to grub, but might apply to all/more bootloaders)
- ldconfig fails due to a issue i still didn't point out
