Yup i'm glad pfsense finally moved to freebsd 10.1 ! that freebsd 8 was so legacy it made the project look "outdated" ;-)
I was able to upgrade one of my boxes just fine and the installer re-installed the packages automagically and all works except unbound … but, i hope somebody replies to my "unbound" post soon :)
I'm just excited that i get to use VMXNET3 now since Freebsd 10 supports it ( on my home machine that sometimes has to deal with 1GBPS routing between VLANs ), other than that ... i guess a "multi core" pf with freebsd 10 is good too !
