Hi,

When running teuthology from a laptop with the configuration below and

./virtualenv/bin/teuthology --archive=/tmp/teuthology try.yaml

it then fails on

./virtualenv/bin/teuthology-coverage -v --html-output /tmp/html   -o /tmp/lcov   --cov-tools-dir $(pwd)/coverage   /tmp/teuthology

Using /tmp instead of /tmp/teuthology here might work if /tmp is
otherwise empty.

This is meant to run on a directory full of results from multiple
tests, and analyze coverage per-test and in aggregate across a suite.
The argument name should probably be changed to be clearer.

I guess I'm not placing the "flavor: gcov" where I should.

I think these days it should go in the install task.
coverage: true still belongs in the ceph task though, so it uses
SIGTERM on daemons.
