Gentoo

For experts only. This script doesn't precisely follow Gentoo Handbook, use at your own risk.

  • uses vanilla-sources by default
  • uses cpuid2cpuflags if CPU_FLAGS_X86 are not manually edited
  • none of the files in gentoo-root/ are strictly required
    • before installation you can remove entire directory instead (although this wasn't heavily tested) and do manual configuration before/after installation.

Prepare

  1. Login to your VPS control panel, go to remote access/VNC page.

  2. Boot VPS instance from any Ubuntu ISO image. Go to step 3 on success.

2.1. If your VPS doesn't support direct boot from .iso, then boot into preinstalled Ubuntu and use netboot:

sh -c "$(curl -L https://omv.codonaft.com)"

Choose 2 → reboot → wait for boot menu → Bootable ISO Image: netboot.xyz → configure network (if there's no DHCP) → Linux Network Installs (64-bit) → Ubuntu → latest LTS version → Rescue Mode.

If this method doesn't work for you—try other ways to boot the netboot.

  1. Before installing, you need a disk with dos partition table and at least one ext4 partition. Optionally you can create a swap partition as well (it will be activated automatically). Something like:
sgdisk --zap-all /dev/vda
echo 'type=83' | sfdisk /dev/vda
mkfs.ext4 -O orphan_file,fast_commit /dev/vda1

You don't necessarily need a completely empty root partition to start installing, however your partition should not contain non-dot directories (other than lost+found).

Usage

  1. Enter to configure the system. Copy ssh keys to gentoo-root/{home/*/.ssh,etc/ssh/} if necessary

  2. C-a 2 → Enter to install the system

Troubleshooting

Failure? Make changes and restart ./03-install.sh

Sudden reboot/etc.? Check /mnt/gentoo/ohmyvps.log
