# PROVIDE: certctl_init
# REQUIRE: mountcritremote
#
# This script ensures that we run `certctl rehash' on first boot of a
# live image to configure TLS trust anchors for OpenSSL in
# /etc/openssl/certs.  We do this only on first boot by testing whether
# /etc/openssl/certs is an empty directory.
#
# Requires mountcritremote for /usr/sbin/certctl.
#
# This is a stop-gap measure to ensure we get TLS trust anchors with
# live images, which we can't prepare at build time because the
# preparation requires running openssl(1) as a tool.  This stop-gap
# measure should perhaps be replaced by a more general-purpose way to
# run postinstall on first boot of the image, but that's a riskier
# proposition to implement on short notice for netbsd-10.
