# steamify-install <target root> <user> [<skip ids>] [gamescope|desktop]:
# runs Steamify's default setup (minus what the installer's Steam Machine
# page leaves out, where the boot page says) for
# the new user inside the installed system (Calamares, after the users and
# services steps). Steamify refuses root and asks sudo per command, so the
# user gets a NOPASSWD rule for this run only, named to be read last: sudo
# takes the last matching rule, and a later %wheel rule would ask again. Never fails the install: a
# problem leaves the log and Steamify can be run again from the desktop.
root="$1" user="$2"
# The pages' ids, comma-separated; the "Everything" entry is an empty id.
