Re: Permission denied during publish

[Chris Warburton]

The problem was that 'asv publish' makes its html output by copying a
'template' directory, then filling in the data; yet this template was
read-only, since we're getting it from the Nix store. Hence we're not
allowed to fill in the data, and we get this permission denied error.

Currently worked around in a nix-config patch, sent upstream to
https://github.com/spacetelescope/asv/pull/521
