Ensure local user Home directories exists

How it is checked

Audit method: Shell command

command -v lsuser >/dev/null 2>&1 || exit 1; out=$( { lsuser -R files -a id home account_locked ALL | while read name ids homes locks rest; do uid=${ids#id=}; home=${homes#home=}; locked=${locks#account_locked=}; [ "$uid" -ge 200 ] 2>/dev/null || continue; [ "$locked" = true ] && continue; [ -d "$home" ] || echo "$name: missing HOME $home"; done ; } 2>/dev/null ); [ -z "$out" ] && echo compliant || printf '%s\n' "$out" | head -n 20

Expected output

compliant
