1.	Somewhere (section 3 maybe?) you need to explicitly state that
we do not support a mixed platform cluster, and that all nodes of a
cluster must transition from bobcat to cougar at the same time.
2.	In Appendix A, I don't believe it would be correct to use the
MAC address marked on the label of the bobcat chassis.  If the system
replaced an existing node in a cluster I believe it would have been
reconfigured to use the MAC addr of the original node.
3.	In Appendix B, note that you need to be careful copying
/onstor/conf/stand_cluster.  The file will not normally exist, so do NOT
generate an error message if it is not there.  However, if it DOES
exist, it MUST be copied.  (The file is created when a node is added to
the cluster, and is used when that node subsequently reboots to
guarantee it doesn't propagate it's clusDb throughout the cluster, but
instead waits to get a valid clusDb from another node.  The file is
deleted after we get a valid clusDb.)
4.	Also, you may need to check what config files are currently
copied from one flash to another as part of an upgrade.  I may be wrong,
but I believe a number of files are missing.  They may not have
equivalent files in linux, but it would be prudent to have a complete
list of the BSD config files and note those that are unnecessary for
linux.

Appendix 12 is missing /etc/group from the bobcat side which needs to be
copied to the cougar as /etc/group and the /etc/gshadow file is created
with grpconv.
