ok. removed gummiboot from ESP via efibootmgr and cleaned up messy entries. Now the box boots 3 OSes via UEFI ... with bootctl coming from the systemd in gentoo. Nice. phew, all that work to resize the ESP from 300M -> 500M. I could have cleaned up old kernels from ESP manually for years instead with that energy/time ;-) thanks all, Stefan
