depot question: clarification about hashes

[Norman Feske]

Hi Johannes,

for reference, these commands work on my machine without error. It's
puzzling.

I think the third hash can be explained: The 'sort' order depends on
your locale settings. Within the depot tools, we use

  export LC_COLLATE=C

You certainly use a different setting on your interactive shell. May you
try your command with this setting?

Still, the fact that extract tool creates a hash different from the one
in repos/base/recipes/api/base/hash is strange. Could you compare the
content of the archive created by you with the content downloaded from [1]?
