I wanted to give funtoo a try. However after installing the system as discribed in the wiki using the better-initramfs and an encrypted root partition, I cannot boot the system properly.
After GRUB2 better-initramfs is giving me following message
Create all the symlinks to /bin/busybox
Mounting /dev (devtmpfs)...
Scaning all disks for volume groups.
No volume groups found
Opening encrypted partition 'sdb4' and mapping to '/dev/mapper/enc_root'.
Device /dev/sdb4 doesn't exist or access denied.
'cryptsetup luksOpen --tries 25 --allow-discards /dev/sdb4
