Pasting Gao's comment here, since I will need to modify the bug description:
------------------------ Much like https://bugs.launchpad.net/ubuntu/+source/linux-azure/+bug/2081613 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2074049 Currently azure kernels override EROFS kconfigs in `debian.master/config/annotations`, so it will cause EROFS doesn't support necessary EROFS compression algorithms for most recent azure kernels (jammy, noble, oracular, etc.) so at least Github action jobs cannot use compressed EROFS at all. e.g. https://git.launchpad.net/~canonical-kernel/ubuntu/+source/linux-azure/+git/jammy/tree/debian.azure/config/annotations?h=azure-6.8-next https://git.launchpad.net/~canonical-kernel/ubuntu/+source/linux-azure/+git/noble/tree/debian.azure/config/annotations?h=master-next https://git.launchpad.net/~canonical-kernel/ubuntu/+source/linux-azure/+git/noble/tree/debian.azure-6.11/config/annotations?h=azure-6.11-next https://git.launchpad.net/~canonical-kernel/ubuntu/+source/linux- azure/+git/oracular/tree/debian.azure/config/annotations?h=master-next they all have ``` CONFIG_EROFS_FS_ONDEMAND policy<{'amd64': 'y', 'arm64': 'y'}> CONFIG_EROFS_FS_PCPU_KTHREAD policy<{'amd64': '-', 'arm64': 'y'}> CONFIG_EROFS_FS_PCPU_KTHREAD_HIPRI policy<{'amd64': '-', 'arm64': 'n'}> CONFIG_EROFS_FS_ZIP policy<{'amd64': 'n', 'arm64': 'y'}> CONFIG_EROFS_FS_ZIP_DEFLATE policy<{'amd64': '-', 'arm64': 'y'}> CONFIG_EROFS_FS_ZIP_LZMA policy<{'amd64': '-', 'arm64': 'y'}> CONFIG_EROFS_FS_ZIP_ZSTD policy<{'amd64': '-', 'arm64': 'y'}> ``` But I hope ``` CONFIG_EROFS_FS_ZIP=y CONFIG_EROFS_FS_ZIP_DEFLATE=y CONFIG_EROFS_FS_ZIP_LZMA=y CONFIG_EROFS_FS_ZIP_ZSTD=y ``` can be enabled just like the ubuntu linux package (see: https://git.launchpad.net/~ubuntu- kernel/ubuntu/+source/linux/+git/oracular/tree/debian.master/config/annotations?h=master- next#n4892) on all platforms rather than just on arm64. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2098178 Title: linux-azure: Recover necessary EROFS compression configurations To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-azure/+bug/2098178/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
