Comment 13 for bug 44233

Update.

I've been reading mount source code. There is no code to handle the udf,iso9660 syntax in it.

So, what we got here is two bugs:

  - install program creates this wrong entry with the comma.
  - support for multiple filesystems on a single removable media device

My above suggestion about patching mount to do so is the best solution I can think of. I do not know if it will break any standard mount may have been built on.

For now, the auto hack should give a working solution for the lucky ones like me who dig into launchpad to find a solution.
