Development
Bug reports, feature requests, help, patches, support and everything else are welcome on the Open Infrastructure Software Mailing List ( <https://lists.open-infrastructure.net/listinfo/software> ).
Please base patches against the 'next' Git branch using common sense ( <https://www.kernel.org/doc/Documentation/SubmittingPatches> ).
Debian specific bugs can also be reported in the Debian Bug Tracking System ( <https://bugs.debian.org> ).
Known limitations
This version of compute-tools currently do not work with systemd-networkd and depend on ifupdown.
Using overlay, the upper directory can not be an NFS mount due to limitations in Linux' overlay filesystem ( <https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/filesystems/overlayfs.txt> ).
