How to determine system is pfSense?

opoplawski

In ansible we're running into an issue where we need to distinguish between FreeBSD and pfSense (see https://github.com/ansible/ansible/issues/41970). What would be the best way to do this?

Not really my field but maybe:

[2.4.3-RELEASE][admin@pfsense.fire.box]/root: sysctl kern.ident
kern.ident: pfSense

vs

root@FreeBSD11:~ # sysctl kern.ident
kern.ident: GENERIC

I would treat only "pfSense" as pfSense and everything else as FreeBSD because custom built FreeBSD is likely to have a custom kernel as well.

Would a uname -a give you what you want ?

[2.4.3-RELEASE][admin@pfsense.xxxxxxxxxx.net]/root: uname -a
FreeBSD pfsense.xxxxxxxxxx.net 11.1-RELEASE-p10 FreeBSD 11.1-RELEASE-p10 #23 r313908+9347c667615(factory-RELENG_2_4): Thu May 10 15:09:29 CDT 2018     root@buildbot2.netgate.com:/xbuilder/crossbuild-243/pfSense/tmp/obj/xbuilder/crossbuild-243/pfSense/tmp/FreeBSD-src/sys/pfSense  amd64

On modern pfSense installs, there are a number of ways. The uname data as already mentioned, the contents of /etc/platform, the presence of the pfSense pkg, and likely dozens/hundreds of other methods based on the presence of certain files around the filesystem specific to pfSense.
