[kernel not starting on an lvm root file system]

The initramfs also needs the lvm progs to be built in, not just the kernel. I use

genkernel --no-mrproper --lvm --no-splash all

maybe try

genkernel initramfs --no-clean --lvm

[ego boot update fails UnicodeDecodeError]

I update every 2nd or 3rd week, if an error i wait a week n try again. This issue has been ongoing a month or so. Have googled a lot and read these forums but at a loss how to fix it. A really old kernel still boots from menu but two recent ones do not. ie ego boot update has failed.  is "manual" grub cmd line available ?

 # ego boot update
