  i did not ... that's necessary?  that's kind of important to know.
let me describe the situation i have to see if BB_SRCREV_POLICY is
actually going to do me any good.

  here's my global site.conf file:

SCONF_VERSION = "1"
SOURCE_MIRROR_URL ?= "file:///home/rpjday/oe/dist/tarballs/"
INHERIT += "own-mirrors"
BB_GENERATE_MIRROR_TARBALLS = "1"
# BB_NO_NETWORK = "1"

so, as you can see, whenever i end up fetching any new source, it ends
up as a tarball and i copy it into my long-lived own-mirrors
"tarballs" directory.  obviously saves me buckets of time.

  now say i've started a new build and i've done all the fetching
without involving BB_SRCREV_POLICY.  i suddenly realize i need to move
to somewhere without network access, so i quickly add

  BB_SRCREV_POLICY = "1"

and do another fetchall to cache all the SRCREV stuff.  it *appears*
that that does nothing for me since all my fetching had been done.

  you're saying i need to cleansstate first, then do the fetchall
*again*?  i might be misunderstanding this but, at this point,
BB_SRCREV_POLICY is starting to look like more trouble than it's worth
since it requires planning, *knowing* that you'll be without a network
later and, worst of all, if you start a fresh build, it does you no
good since all that cached SRCREV content is in the other build
directory's tmp directory.

  given that all of this can be avoided by just avoiding tag names,
i'm liking that option more and more. :-)
