First Steps After Installing AcreetionOS

Fresh install? Run through this list once and your system is dialed in.

1. Update everything

Even a fresh ISO may be a few days behind the rolling repo:

sudo pacman -Syu

Learn what the flags mean in Updating the System.

2. Let Timeshift take a snapshot

AcreetionOS pre-configures Timeshift with RSYNC snapshots during install. Confirm a baseline snapshot exists now — if an update ever misbehaves, you roll back instead of reinstalling:

sudo timeshift --create --comments "clean baseline"

Details: Timeshift Snapshots. If things do break: Recovery Environment.

3. Turn on the firewall

sudo pacman -S ufw
sudo ufw enable
sudo ufw status verbose

More options: Firewall Basics.

4. Add your daily user (if you skipped it)

The installer creates your user, but double-check sudo access:

groups          # you should be in 'wheel'
sudo whoami     # should print root

User management reference: Users & Sudo.

5. Install your everyday software

sudo pacman -S firefox libreoffice-still vlc

Browsing tip: the Pacman Cheat Sheet covers 95% of day-to-day commands, and AUR & yay unlocks the rest of the Arch ecosystem.

6. Optional but nice
