If the issue is that only POST_INSTALL runs on DKMS < 2.2.1 and both run on
DKMS >= 2.2.1, couldn't we modify POST_INSTALL to include an existence
check for the build dir before attempting the cp, and then include both
POST_INSTALL and POST_BUILD steps?
That way, the POST_INSTALL step will silently bail on DKMS >= 2.2.1
(because the existence check for
${dkms_tree}/${PACKAGE_NAME}/${PACKAGE_VERSION}/build
would fail), and POST_BUILD would copy the files over, while on DKMS <
2.2.1, POST_INSTALL would happily succeed?
Something like
POST_INSTALL="if [ -d \"${dkms_tree}/${PACKAGE_NAME}/${PACKAGE_VERSION}/build\"
]; then cp ...;fi"
POST_BUILD="cp ..."
?
