Lots of kernel installation failures with very long signatures:

• https://errors.ubuntu.com/oops/024acb70-836a-11e2-9a69-e4115b0f8a4a

• https://errors.ubuntu.com/oops/19c416f4-87ab-11e2-9621-2c768aafd08c

Discussed duplicate signatures:

• https://bugs.launchpad.net/ubuntu/+source/dpkg/+bug/1096928

Actions

• Do not include the log as part of the identifier.

• Bucket installation failures with "package:", followed by the package, package version (to be installed), and error message (ErrorMessage field).

• Provide a specific bucket identifier for file name conflicts during package installation. Do not include the package version number in these.

• Fix DKMS to not attach the whole build log as a signature. Pull out just the first line? (Bug 1175785)

• Filter all of these out of the phased updates "new buckets" query if they can produce a new signature without actually changing (package version changes, installation under another language).
