So in a nutshell, you are saying that AUFS is quite stable in FreeBSD-6.2?

As Henrik mentioned, I will only need the following compilation options for using AUFS for squid:

'--enable-storeio=ufs,coss,diskd,aufs,null'

I don't need any extra compilations to use AUFS besides the above?

I also don't need to apply the patches regarding the "Kernel Panic" bug mentioned above in FreeBSD-6.2 right?

Is that correct?

Thanking you...
