when banging on this months ago, i was told that while this works as advertised, you simply don't _see_ that it works by looking in the filesystem. at that time, i did confirm this by seeing the unchanged file in the filesystem but also seeing changes in system operation due to the module that i passed via grub. so ... can you dis/prove the change based on something other than looking at the file? perhaps a change in your DNLC operation? ------------------------------------------- smartos-discuss Archives: https://www.listbox.com/member/archive/184463/=now RSS Feed: https://www.listbox.com/member/archive/rss/184463/25769125-55cfbc00 Modify Your Subscription: https://www.listbox.com/member/?member_id=25769125&id_secret=25769125-7688e9fb Powered by Listbox: http://www.listbox.com
