Modified Files:
        src/sys/kern: vfs_mount.c

Log Message:
vfs_mountroot(): don't needlessly grab a second reference to the root vnode
(the kernel never chdirs) nor a lock on it.

So the kernel chrooting to sysctl init.root is still ok?

How is that accomplished?  I couldn't find the code and don't recall seeing

sysctl -w init.root=/altroot

See the ZFS Root ramdisk:

I tested kernel from yesterdays sources and it still works fine, so I guess nothing was needed here.
