braindump for windows

this isn't meant as a solution, but as a place to experiment with window support (as time permits)

symlinks apparently work if:

- [x] the user is an admin (confirm)
- [ ] the users policy allows them (couldn't get this to work)

with more hacks i was able to get ^^ sorta booting, but I ran into other problems (like missing files) and I failed to have time to investigate further today
Also need to unlink `canLinkSrc` here.  Otherwise it is only removed if an error occurs during symlinking.
