// Creates a read-only snapshot of the booted profile before apt changes packages, tagged
// apt-<action>. Runs only when apt is about to call dpkg; $PPID is the apt process, so its cmdline
// gives the subcommand. The case is the allowlist we protect. Skips build-time chroot apt; never
// aborts apt. Single line: apt.conf strings cannot span multiple lines.
