yes we know which one - ${B} as defined in deploy.bbclass:
do_deploy[dirs] = "${DEPLOYDIR} ${B}", and the same is defined again (maybe
unnecessary) in
kernel.bbclass
DEPLOYDIR is defined in deploy.bbclass as well
DEPLOYDIR = "${WORKDIR}/deploy-${PN}"
DEPLOYDIR is used as target for every other file deployed by do_deploy,
this was just unnecessary switching CWD to create relative symlink and I
have no idea why rm -f was used together with ln -sf.
I'll send v2, because
ln -sf ${MODULE_TARBALL_BASE_NAME}.bin ${MODULE_TARBALL_SYMLINK_NAME}
is wrong.

I suspect the answer is absolute path, but this is a good example of where
a proper comment is useful.

Please include a a comment. The burden is on the submitter to prove
the cd and the rm are unnecessary, not the reviewer.

So we are now in a different directory (do we know which one?) but the
source of the ln commands doesn't change. If we are in the same
directory, then why add DEPLOYDIR to the destination?
