Caching itself is relatively easy (just implement an equivalent of tee inside pack-objects ourselves). More problematic is pruning. We could do it from cron based on atime _if_ the filesystem is not mounted noatime but without arranging a reasonably way for automated pruning this would become a disk hog and extra maintenance burden, which is why I did not implement the dynamic caching part in the initial round. Since git-daemon would be the primary user of pack-cache/, this implies a repository writable by git-daemon user on public machine (not master), which is an extra thing to note. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
