site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com Hi Folks, Thanks for the debugging tips. Now for more detail because the debugging isn't helping. :-( I'm writing a file system filter scheme loosely based on SampleFilterScheme. Unfortunately SampleFilterScheme appears to predate GPT (Intel) boot drives. I'd like to have my filter scheme attach to GPT volumes including the system volume. I have been unable to make this happen with the SampleFilterScheme. I have modified the SampleFilterScheme to recognize the HFS partitions of GPT drives. Including code overriding probe() to protect against circular conditions (it advertises what it attaches too). This works fine for non-system disks. If I enable Local-Root including the attach/detachMediaObjectToDeviceTree () code then the system hangs at startup. Verbose mode says "Waiting for file system to mount" or something close. I don't see any logging from the filter scheme at all, but clearly the system is unhappy. Any clues? Has anyone successfully attached a filter scheme to a GPT boot volume? Thanks for any help, ...Duane _______________________________________________ Do not post admin requests to the list. They will be ignored.
