  should one still change the NAME or DESCRIPTION comments in that new
mymachine.conf file to reflect "mymachine" as the dev-manual suggests,
or can one just leave them referring to crownbay?  recall that the
current dev-manual claims that you "need" to make those changes.  if
you don't, that claim should be softened.

  also, there's no mention of editing "layer.conf" to reflect
"mymachine" as directed in dev-manual:

  BBFILE_COLLECTIONS += "mymachine"

should that not be done?  again, the current dev-manual states that
that change is "needed".

  don't you also have to rename "crownbay-noemgd/" to "mymachine/"
under that recipes-graphics/ directory as well, as the dev-manual
directs?  you don't mention that here.  you also don't mention making
editing changes to recipes-core/tasks/task-core-tools.bbappend as
dev-manual suggests.  not necessary?

  ok, just took that verbatim.

  other than sourcing from one directory level up and making the
appropriate changes in conf/local.conf to refer to "mymachine", no
difference here.  just started the build ...
