? OK, I load the kernel from the JFS. I mount the root FS, which is a JFS. I read the module "jfs.ko" from the JFS so that I can mount the root FS, which is a JFS, so I can read the module "jfs.ko" from the JFS so that I can mount the root FS, which is a JFS, so I can read the module "jfs.ko" from the JFS so that I can mount the root FS, which is a JFS, so I can...

I was under the impression that it was there for Linux compatability. My impression is, layout or not, the original JFS is much better code, overall. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
