 with a custom built one, when the system is functional. If you are looking for a way
 to detect and manage your kernel configuration, have a look at [autokernel](https://github.com/oddlama/autokernel).

-* Does everything minus something
-* Partition disks (supports gpt, raid, luks)
-* Download and cryptographically verify the newest stage3 tarball
-* Extract the stage3 tarball
-* Sync portage tree
-* Configure the base system
-  - Set hostname
-  - Set timezone
-  - Set keymap
-  - Generate and select locale
-  - Prepare `zz-autounmask` files for portage autounmasking
-* Select best gentoo portage mirrors
-* Install git (so you can add your portage overlays later)
-* Install `sys-kernel/vanilla-kernel-bin` (temporarily, until you replace it)
-  - EFI: Copy kernel to efi partition
-  - EFI: Create boot entry using efibootmgr (or install syslinux for BIOS boot)
-  - BIOS: Install syslinux
-* Generate fstab
-* Ask for a root password

 Also, optionally the following will be done:
 
 * Install sshd with secure config
-* Install dhcpcd
+* Install dhcpcd (only for OpenRC)
 * Install ansible, create ansible user and add authorized ssh key
 * Install additional packages provided in config
 
 Anything else is probably out of scope for this script,
 but you can obviously do anything later on when the system is booted.
