Who's patching open source?
Companies that provide third-party support for open-source software can be divided into two groups, roughly speaking.
In the first group are what could be called "professional services companies" -- those vendors who provide support for a specific platform. An example is Progeny, which now patches the versions of Red Hat the leading Linux vendor no longer supports.
The second group is comprised of management companies -- firms that build software to administer the open-source stack. An example is Covelent, which builds an application that provides a user interface to manage the full stack of open-source programs.
The division between these two types of vendors is far from clear. In some situations, Covelent provides patches for software it did not write. And Progeny -- if it has built a custom distribution for a customer -- provides management.
