Re: Goa: Cannot get sub-node from XML

Hi Rumen, I was also wandering how to add lx_block to my runtime. I cannot seem to find the corresponding depot url to put in my archives file. The closest I found was _/src/lx_block in repos/os/recipes/pkg/test-lx_block/ archives, but from what I can tell that is relative to test-lx_block.

Re: Goa: Cannot get sub-node from XML

Hi Rumen, I gave this a test run and noticed that your runtime file is very odd. First of all, there are multiple start nodes but it also mentions 'binary="squid"'. I guess the runtime is rather indented to use init, hence you'll need to add 'binary="init"' instead. In this case, the XML prov

Hi Rumen, the error message is actually expected in this case. Since the VFS in this example is static (i.e. immutable), fs_query fails to set up a watch handler. However, it still outputs the directory listing correctly. If you change the '' into '' to make the VFS mutable, the error message
