Three changes to the question at the top of the run. USER_HOME is looked up rather than assumed. The original built "/home/$USERNAME", which is only the usual answer — an account created with a different home, or one whose home was moved, had every later step writing to a directory that was not theirs. getent passwd knows; the /home guess remains only as the fallback for an account that does not exist yet, where there is nothing to look up. The default is now whoever invoked sudo. On a re-run, or on a machine that is already somebody's, that is the answer every time, and retyping it is a chance to typo it into creating a second account. root invoking the script directly offers no default, since root is never the account being set up — and is refused if typed. The name is validated against the portable shape of a Linux account name before anything else happens. Letting adduser refuse it later means several questions have already been answered against a name that was never going to work. It also no longer goes through prompt_value, which obeys any environment variable matching the name it is filling in. USERNAME is set by some login environments, and a variable this script silently takes as an answer should not be one that might already be set for unrelated reasons. SETUP_USERNAME is the explicit override. The tmux config write moved out of the user section entirely. It was there only because the original copied it right after adduser, where $USER_HOME first exists. It is a dotfile and belongs with .zshrc and the starship config in the shell section. Verified: defaults to the sudo invoker, resolves daemon's home to /usr/sbin rather than /home/daemon, falls back to /home for an account that does not exist, and rejects a name with a space, a leading digit, one over 32 characters, and root.
