You mean with a space in the version string ? I know that I don't want
directories floating around
with spaces, since they cause no end of troubles. But maybe it's just the
font in gmail playing
tricks with my eyes.
Perhaps Richard has a suggestion, but in 3+ years, this is the first time
that this particular issue
has come up. Most everyone is setting the PREFERRED_VERSION in their bsps,
or local.conf
and not using that particular mechanism of switching between kernels ..
myself included, and I
probably build more versions of linux-yocto than anyone you'll find :)
Don't get me wrong, I'm not dead set against changing it, but we do need
both the meta and
machine git hashes in the version to uniquely identify the tree (and my no
spaces comment!).
Maybe someone knows of a better way for command line switching of the
version ?
