(the mailing list didnt accept this, retrying) Ok I spent some time looking at ways of building config files into images more easily, ideally without bringing in too much file system handling eg if you just want a few files to serve on a web server or some network config like DNS setup.
So I have made a simple tar extraction library (largely by deleting code) that is easy to compile and link. https://github.com/justincormack/libuntar It is less than 10k compiled, still needs some more cleanup but the simple cases work (decompression needs a bit of tidying). It supports GNU or BSD tarfiles, and supports device nodes, soft and hard links etc. The mem/ directory has an example - add an image.tar file and it will make a standalone executable that when run will untar the tarfile that is linked into its binary. This runs on linux/netbsd7/rumprun-posix fine and will populate the root fs, and should be trivial to add into a Xen/baremetal image, just remove main() and call extract() after rump_init().
