Attic fails to build with fatal error: uds-remote-store.md: No such file or directory

I tried to update to current master on nixpkgs today for my systems but encountered the following error:

Maybe this has something to do with the recent nix update?
If I can do something more to help debug this issue, please let me know.

So, I guess it does have something to do with the recent update to 2.15.1 on nixpkgs..

When testing the above fix to nix I ran into the following issue:

Any idea where this comes from?

EDIT:
Please ignore the version identifier of nix. I overwrote it to test my fork which included the fix

[zhaofengli]

I'll take care of this in a bit.

For reference, this was fixed upstream in NixOS/nix#8493, but let's work around it downstream while we wait for a release.
