# nixos-rollback.sh # auto-detect & set previous gen

# nixos-rollback.sh --dry-run # show what would be done
|

# nixos-rollback.sh --rollback-now # also run nixos-rebuild switch

#
|

# Exit codes:

# 0 — rollback applied (or dry-run would apply)

# 1 — preflight failure (missing files, permissions)

# 2 — no previous generation available

# 3 — nixos-rebuild --rollback failed (only with --rollback-now)

#
|

# Installation on NixOS:
|

# Place in /usr/local/bin/nixos-rollback.sh and make executable.
|

# Add a systemd oneshot service to run it after sentinel-check detects

${CYAN}DESCRIPTION${NC}
|
||||
Reads the current default boot entry from ${LOADER_CONF},
|
||||
determines the previous generation number, and writes it as the
|
||||
new default. The script only modifies systemd-boot config —
|
||||
it does NOT touch the Nix store or system profile unless
|
||||
--rollback-now is passed.
|
||||
|
||||
Designed as the rollback half of a boot sentinel:
|
||||
1. System boots into generation N
|
||||
2. sentinel-check.sh detects Tier-1 service failures
|
||||
3. nixos-rollback.sh sets default to generation N-1
|
||||
4. Next reboot uses the working generation
|
||||
|
||||
