Packages and Compact Flash
I did some research but I'm not quite sure about the answer to this.
If I use a CF image instead of installing to a HDD from the live CD can I still install packages?
I'll be using the 4GB image.
Some of them are disabled and some are available but don't work right. You should verify that the ones you want are working under pfSense NanoBSD.
However, you can do a full install onto CF, which is what the OP asked about. There are just things to be aware of, all of which can be easily found by searching the forum.
