If something goes wrong inside cenbuild, you may want to use some debugging tools to figure out what happened. E.g. strace and gdb. Unfortunately, you generally cannot use the system tools for this because of the complex chain of subprocesses and sudo from cbrun. Instead, it would be useful if we had the relevant tools inside cenbuild. They could then be executed after the magical transition to the chroot.
On practical detail is how these would be built and installed. Every other package we have is because it is needed to build ThinLinc. That would not be the case here, so where do we put the "Requires:" for these pacakges?
