New Revision: 343354
URL: https://svnweb.freebsd.org/changeset/base/343354
Log:
Remove extraneous setutxent() calls in write(1).
We already call setutxent() once during initialization. Furthermore,
the subsequent calls occur after the process has entered capability
mode, so they fail, and attempts to fetch database entries fail as
a result.
