DBCIOCUID(9)

💖 NAME 💖

okay so bestie, this is DBCIOCUID(9) from the Kernel API Manual — the page all about setting the user ID (UID) of a calling process. The user ID is 8 bytes long. It must be programmed using a 32 byte signature built using the nonce fetched from DBCIOCNONCE. The UID can only be set once until the system is rebooted — one shot, no take-backs, periodt. 💅

⚠️ fr fr though: once it's set, it stays set until reboot. plan accordingly, bestie.
