Subject: Switch to stdio-based I/O for writing descriptor file.
X-Git-Url: https://git.vrable.net/?a=commitdiff_plain;h=977ee3e11dfea651ed87d92c001067158b7c2ba8;p=cumulus.git

Switch to stdio-based I/O for writing descriptor file.

This should be a little bit easier to hook into filtering code (we can open
the output file, spawn the filter, and then fdopen the resulting
descriptor), which will be used when implementing signing of the descriptor
files.
