I have been trying to set up GRUB to boot Linux from an LVM logical volume on top of a LUKS device. This is my system root partition, including /boot. I've read various places that GRUB2 supports booting from LVM or LUKS volumes, but nothing that seemed too official or that mentioned both at the same time. Is this a supported configuration?
My current status is that I can boot GRUB, GRUB will ask for my encryption key, and show the boot menu (from grub.cfg stored in /boot) after I give my key. At this point, I can see from the GRUB shell that GRUB has mounted my LVM/LUKS volume, and I can see my kernel and initramfs in /boot. I can give the initrd and linux commands seemingly without error. But when I give the boot command, the system just hangs. Any ideas?
