Description Richard Purdie 2012-01-27 02:25:59 UTC 
If sstate packages are build on a system with a specific glibc version, there should be some way to detect when they're installed on an older system and at least flag the packages as invalid.

Running against newer glibc shouldn't be an issues, its just a question on detecting and invalidating running on older glibc than the package was built for.
Comment 1 Richard Purdie 2012-07-26 13:20:56 UTC 
For now, the best approach is going to be to mark sstate packages as being built against a given lsb_release name/version.

There are patches our for review which do this.

Changing distros will cause bitbake to make a new directory in sstate-chache with distro name and version in which to store its native and cross packages.

Example: 
/build/sstate-cache/Ubuntu-12.04/*/sstate-*-native-*.tgz
/build/sstate-cache/Ubuntu-12.04/*/sstate-*-cross-*.tgz
