Hi, a new morning... :) Being on the way to install/setup the base system (mostly getting stage3 uptodate) I came accross kinda inconsistency -- or at least it looks like for me. The system uses a 3T harddisc (and later a SSD) and therefore GPT. GPT is the sister/brother of an U/EFI boot. For that the documentation (AMD64 handbook): https://wiki.gentoo.org/wiki/Handbook:AMD64/Installation/Disks#Using_UEFI says: Default partitioning scheme Throughout the remainder of the handbook, the following partitioning scheme will be used as a simple example layout: Partition Filesystem Size Description /dev/sda1 (bootloader) 2M BIOS boot partition /dev/sda2 ext2 (or fat32 if UEFI is being used) 128M Boot/EFI system partition /dev/sda3 (swap) 512M or higher Swap partition /dev/sda4 ext4 Rest of the disk Root partition and later on at https://wiki.gentoo.org/wiki/Handbook:AMD64/Installation/System FILE /etc/fstabA full /etc/fstab example /dev/sda2 /boot ext2 defaults,noatime 0 2 /dev/sda3 none swap sw 0 0 /dev/sda4 / ext4 noatime 0 1 /dev/cdrom /mnt/cdrom auto noauto,user 0 0 Here /boot changes from fat32 to ext2. Since this is my first U/EFI system I am a little confused. Currentlu it looks like the vmlinuz binaries will be installed on a FAT32 filesystem. Since the kernel can be launched from a ext4 filesystem I cannot see, why this have to be a FAT32 filesystem. My plan (if this is possible), is to U/EFI-boot grub, from which I can select the kernel in question as it has been on my old system (MBR based). My current partition table looks like (only relevant parts shown): Number Start End Size File system Name Flags 1 1049kB 3146kB 2097kB grub bios_grub 2 3146kB 137MB 134MB fat32 boot boot, esp 3 137MB 674MB 537MB linux-swap(v1) swap 4 674MB 269GB 268GB ext4 root What did I messed up here? Cheers! Meino
