I’m an arch user, and also have a small proxmox based homelab. I always have a live Ubuntu around, the latest desktop version available. Good for troubleshooting. Also, latest proxmox, opnsense, pfsense, debian.
Additionally, I have a small USB drive on my keychain with both USB C and USB A, where I keep some encrypted backups of important stuff, and I can access that from both my laptop and my phone.
