Linux -> VMS is not that unusual.

But the typical context is:
* There is one or more primary applications running
   on VMS - something business critical
* Either there is no plans to migrate off VMS or
   the plans are far out in the future
* There is a need to get one or more supporting
   applications that exists for Linux running on
   VMS to add value to the primary application(s)
* Building the Linux C/C++ code on VMS turns out to be
   very difficult:
   - VMS compilers are behind current language standards
   - often the *nix build processes uses some tools that
     has not yet been ported to VMS
   - code uses *nix specific features with no obvious
     VMS counterpart
