Would this break some tools? (If distribution > packagers use tools to automatically detect when a new release is > available, would such a change break these tools?) Not speaking for the distributions obviously, but I have no objection to dropping the per-component tags if they aren't being used and are causing confusion. A bit of historical context: originally, we released the selinux userspace as a single tarball with a single date-based version. When SELinux was first being integrated into Fedora, the Fedora packagers wanted releases to be split into separate source tarballs for each component each with its own independent version, so this was done for formal releases but the source continued to live in a single source code repository. (This all predates the move to GitHub, of course). The individual component versioning has limited utility in my view given that there is almost always at least one source level change to every component between any two releases and there tends to be a strong coupling among many of the components. In the past, we have considered either going back to a single source tarball with a single version, or splitting the source code repository itself to be per-component. Either approach would allow direct use of the github releases as the official release mechanism and avoid the need to separately create and maintain the release tarballs on the wiki pages. _______________________________________________ selinux mailing list -- selinux@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to selinux-leave@xxxxxxxxxxxxxxxxxxxxxxx
