network CA cert

[gkusiak]

should I install my network's ca.crt on my xbian unit? it has been working quite well without it - how might that change if I were to proceed?

(this is also opening a small door to my next question about VPNs and kodi/xbian...but first things first, right?) It may be taken for granted around here that it's the way to proceed, but I'm just looking for a bit of confirmation. I already encrypt my DNS lookups on a network basis (DNS-over-TLS and CloudFlare - a big improvement over my ISP), so putting that inside a tunnel would make for gold-standard (to the best of my knowledge/understanding) privacy and possibly network security.

I'm hoping there is someone here with experience/expertise to offer insight.

Thanks in advance!
