Actually, I was surprised how well the Windows Subsystem for Linux actually works. Yesterday I even compiled some Ubuntu packages (using C++, Qt, Boost, etc.) and submitted them to my PPA on Launchpad. From Windows!
The good news is that a lot of these things are getting fixed. E.g. it used to be that path expansion for executable files lookup didn't work too well (as in, you could launch native Windows executables only via direct path, because the subsystem would otherwise check for an ELF header, so you couldn't launch foo.exe in your $PATH just by name), but I understand that this is getting changed in upcoming releases.
I'm keeping an eye on this thing, it is promising. I'm so looking forward to putting all the Red Hat-branded breakage behind me and not have to wrestle with my computer all day.
But I agree that it would be great if they could solve this in the future.
