It seems to me I'm missing some key point...
I'm building everything in chroot on x64 for x86 (using CLFS as a
base). I've tried booting from GPT on Atom and HP desktop with Core2
(grub loaded, menu shown). After selecting menu (as Bruce suggested) I
always get a kernel crash during boot on both Atom and Core2 pc. Only
if I add initrd I can boot linux.
When I make LFS/BLFS bootable, do I keep kernel file in rootfs./boot
or in a separate grub /boot partition?
Do I still need rootfs:/boot? In case yes, why do I need 200Mib /boot partition?
In grub,cfg do I use "root=PARTUUID=xxx.." or "root=UUID=xxx.." ?
Regards,
Alexey
