pfSense is FreeBSD underneath, but the FreeBSD package does not work there, failing in three silent ways. pfSense runs only /usr/local/etc/rc.d/*.sh at boot and re-runs them when WAN gets a new address, so a suffixless rc script never starts; unbound.conf is generated from config.xml with no conf.d, so a drop-in is never read; and on a firewall where the default-on "Allow IPv6" has been turned off, unbound is then generated with do-ip6: no and a responder on ::1 is unreachable. So this ships fips.sh, wires the fips. zone into the DNS Resolver through config.xml, and binds the responder on 127.0.0.1 for robustness against that last case. The rc script is plain sh: what pfSense imposes is the .sh name and that a re-run leave a running daemon alone and exit 0. It identifies the daemon by process name and recovers an orphaned daemon(8) supervisor found via fstat, since a locked empty pidfile makes daemon(8) report pid -1. The DNS setup is a manual step, never run from post-install, and validates the merged options with unbound-checkconf (pfSense's test_unbound_config) before touching config.xml, so a bad merge cannot take DNS from every client behind the firewall. The daemon runs under daemon(8) -H so newsyslog can rotate its log by signalling a reopen. Packages link statically by default: pfSense runs a FreeBSD base that cannot be obtained to link against. A firmware upgrade keeps the package (pfSense-upgrade removes only pfSense-pkg-*; confirmed on a live Plus 26.03.1 -> 26.07 upgrade, aarch64 — the package survived and the daemon restarted at boot. That is a minor, FreeBSD 16 -> 16 change; the cross-major compat case is still only source-reasoned). aarch64 is refused, where a static binary faults at posix_spawn. The mechanics the two builders share — version derivation, the stage layout, the manifest fields, the @sample scripts and pkg create — live in packaging/common/pkg-lib.sh, which both source; the FreeBSD package is byte-identical before and after that extraction. One ABI can serve more than one product: CE 2.9 and Plus 26.x on Intel are both FreeBSD:16:amd64 with a byte-identical artifact, named ...-ce2.9-plus26-amd64.pkg. The pfSense package is built and checked in its own CI job — separate from the FreeBSD package, and not a dependency of the release job, so a pfSense-only failure reds that job alone and is never a release asset. It is kept as a workflow artifact until it has been installed on a real pfSense box. CI produces the CE 2.8.1 (FreeBSD:15:amd64) package; CE 2.9, Plus 26.x Intel and ARM need a FreeBSD 16 build host the CI does not have, and ARM stays build-it-yourself because rustup ships no toolchain for it. testing/check-pfsense-pkg.sh validates a built package on any FreeBSD host and runs in that CI job: contents, modes, a positive boot-script lifecycle against a stub daemon, php -l and a fips_strip_block unit test of the config.xml helper. Installing on a real pfSense box, and the firmware-upgrade behaviour, are covered only by an aarch64 hardware run and pfSense-upgrade's source; the README records what is and is not tested.

# newsyslog(8) rotation for the FIPS daemon log. Installed by the package
|
|
# under /usr/local/etc/fips and copied by fips.sh into
|
|
# /var/etc/newsyslog.conf.d/fips.conf on every start, because pfSense
|
|
# regenerates /etc/newsyslog.conf itself and, on a box using RAM disks,
|
|
# rebuilds /var/etc at boot — a file put there by pkg would not survive.
|
|
#
|
|
# 5 generations, rotate at 1000 KB, compressed (J = bzip2), C = create the
|
|
# file if missing. The pid file is the daemon(8) supervisor's, so after
|
|
# rotation newsyslog sends it SIGHUP; daemon(8) is started with -H, which
|
|
# makes it close and reopen its -o output file on SIGHUP. Without that the
|
|
# daemon would keep writing to the rotated inode, and once the compressed
|
|
# generation is unlinked it would write into a deleted file — on a RAM-disk
|
|
# /var, space never reclaimed and /var/log/fips.log left empty.
|
|
# logfilename [owner:group] mode count size when flags [/pid_file] [sig_num]
