We used to use LSB_DISTRO_ADJUST to stop Debian minor release upgrades causing sstate paths to change up until about five years ago when we upgraded to an oe-core version that only considered the major version to be important. > I did have a look at > https://git.yoctoproject.org/poky/commit/meta/classes/base.bbclass?id=096306ecd1bb80fe5e732584caca0172305628a2 > where it was introduced 10 years ago but there isn't much more info. I believe that we use the mapping in SSTATE_MIRRORS to do the equivalent of what is described in that commit message: SSTATE_MIRRORS ?= "\ file://debian ${OUR_SSTATE_DIR}/debian-10 \n \ file://debian-11 ${OUR_SSTATE_DIR}/debian-10 \n \ file://debian-10 ${OUR_SSTATE_DIR}/debian-10 \n \ \ file://debian-9 ${OUR_SSTATE_DIR}/debian-9 \n \ file://.* ${OUR_SSTATE_DIR}/PATH \n \ " (Our autobuilders are running Debian 10 at the moment, so anyone running Debian 11 can make use of sstate files they wrote to debian-10, but anyone running Debian 9 cannot.) I have no idea whether this works for the Red Hat world though. HTH. Mike.
