Testing changes to loader.conf.local

[casper1980]

Hi,

I've been looking at making a number of changes to the improve my Opnsense IPS performance. I have seen a number of suggestions with sample loader.conf.local files etc. It got me thinking about how I might safely test these without hosing my system. I have been trying to find some way of specifying an alternate loader.conf file to no avail but did wonder if nextboot might be the way. Can I use nextboot.conf as a temporary loader.conf.local? I can't find it being used to test anything other than an alternate kernel but hoped it would work for me in this case.  Has anyone got any advice?
