Did I make the right decision?

At the start of this process I decided to use the Centos ISO for installing FusionPBX.  Well, I'm beginning to question this decision now for the following reasons:
1. although I can update the FusionPBX code very easily with a single button to press, I cannot update the Freeswitch version without learning how to compile updates from git.  This is because there are no updates available for FusionPBX using a package manager in Centos at this time.
2. There are permission issues in the Centos image - as you will have already seen earlier in my blog - I've fixed some of them but I suspect that there are others as there are still some things that don't work right.
3. It seems that Centos is not the most efficient OS and takes more memory to function well than something like FreeBSD does.

So I'm looking to change to FreeBSD.  Actually to be more precise, I'm looking to change to pfsense because this runs on FreeBSD and actually uses an even more stripped down version of FreeBSD so that it runs with less memory.  Doing this apparently solves all the problems I've identified above.  I'm going to start by trying pfsense 1.2.3 not pfsense 2 as I understand it isn't quite working well with version 2 yet.

UPDATE: Well, I've installed pfsense a few days back (using the download here: http://www.pfsense.org/index.php?option=com_content&task=view&id=58&Itemid=46) and loaded fusionpbx on top of it (using these instructions: http://wiki.fusionpbx.com/index.php/PfSense_Install#pfSense_1.2.3_or_pfSense_2.0).  I'm still fiddling with the setup a little and experimenting with it and when I'm happy I'll post more details.  For now the update is that it seems to be good, although I think I may have a permission problem right now that I need to overcome and document.  One of the nice benefits that there seems to be is that pfsense appears to come already setup with OpenVPN which means that once I have that up and running remote administration should be very straightforward in theory, though I haven't tried it yet.

Warning: I have been informed that there is a problem running fusionpbx on an embedded version of pfsense - apparently due to the file system used by pfsense, some data is lost when the machine is rebooted and this impacts the operation of fusionpbx.  This issue apparently does not apply to pfsense installed on a harddrive though.

My conclusions may not suit you.  You need to work out what is important to you and to test it yourself!
