# Re-size the PHP-FPM pools and the Apache MPM to whatever the box looks like
# now. Adding or removing a site changes which PHP versions need a warm pool,
# and nothing else notices: a version that stopped being used keeps its workers
# for as long as the server stays up.
#
# Safe to run unattended — it is a no-op when nothing changed (it stamps the
# config content it has loaded and compares against that), it validates with
# `php-fpm -t` / `apache2ctl configtest` before reloading anything, and its
# max_children figure has hysteresis so a couple of MB of sampling noise cannot
# make it flap. Weekly, off-peak.
