Hmm it's not meant to be supported but it should be an error, not an unreachable

Having symlinks doesn't seem too odd, but FWIW, I'm also seeing this error when modifying config.toml (... "unexpected path: "/config.toml""). This is on Windows v0.14.1 installed from Scoop, and the config file is a normal file in the site root, not a symlink.

IMO, the least surprising thing to do is that if you aren't sure, regen everything.

The config one is a bug that is fixed in the next branch.

@Keats Won't symlinking content files be supported?
