First of all, I know nothing about LVM, and, therefore, my remarks might be out in “left field." I’m assuming that your LFS exists on a *real* hard drive in a *real* partition. LFS, in and of itself, does not need an initrd.img to boot. If your LFS is on a real partition on a real hard drive, then you should be able to boot the kernel from grub. When I’ve been dumped to a shell “sh-4.3” with the same error message, it was the result of the kernel trying to use the wrong partition for /. I believe that when you are in a grub shell using the command line before boot the correct command is: set root=(hdx, <some partion name>y) I recommend using the grub completion ability if you don’t know exactly where your LFS is. Try this from the grub command line: set root=(hd [then hit TAB to get your choices] , then set root=(hd <whatever you selected when you hit TAB above>, [hit TAB again to see the partitions]. Keep doing this until you get a complete “set root=“ command then linux /boot/vmlinuz3.16.2-lfs-7.6 ro root=/dev/<whatever device there is> [the /dev/ device where your kernel is] boot I see what I think are two errors in your “grub commands” : it should be set root=<something> and there is no /boot/vmlinux….in your linux command. The format for these commands can be *slightly* different on the command line compared to what you use in grub.cfg. Hope this helps.
