The AcreetionOS Recovery Environment

This is the feature people write home about. The AcreetionOS Recovery Environment is a maintenance mode built into your install — no USB hunting required.

Getting in

GRUB menu → "AcreetionOS Recovery Environment" entry (press F9 hotkey where provisioned).
Failover: if boots keep failing, the tracked-default mechanism drops you there automatically.
From the live ISO: same entry exists on the installer media.

You’ll land in a green-on-dark TUI matching the AcreetionOS brand.

The ACRECOVERY partition

During install, if free space allowed, AcreetionOS provisions an ~800 MiB self-contained ACRECOVERY ext4 partition: its own GRUB plus kernel/initramfs copies, chainloaded from the main bootloader via F9 or grubenv failover. It survives even a destroyed main /boot. A pacman hook keeps its kernels synced on updates; retrofit it anytime from the live ISO with:

sudo acreetion-recovery-setup --auto

When recovery can’t help

Total hardware failure, or an encrypted disk whose passphrase is lost. For everything else, this menu plus good backups covers ~every disaster scenario.
