For those who load modules dynamically because they don't want to recompile kernel this is not a solution. My practice is to load modules dynamically to share the same kernel between several boxes. One of this PCs works as a firewall, another one serve my personal CVS repository and works as a test box (there are other machines running -CURRENT and virtually all use the same kernel and modules). Some time ago I tried to upgrade IPFilter on the fly (kldunload && kldload) and it worked like a charm. It is an endless discussion, and I really don't want to continue. I wrote a letter because I disagree with Crist J. Clark > CJC> Both. If you are getting an 'Exec format error,' there is > CJC> something wrong at your end.

It depends on pfil(9). Sincerely yours, Sergey Mokryshev. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
