Summary and Info:

I'm quoting Andrew Gregory from  FS#49816 :

- Hooks are run with SIGPIPE ignored which causes '... | grep -q ...' in the dkms script to print the error when the grep exits early and the echo receives EPIPE.
- does not ignore SIGPIPE, GPGME does. I need to look into resetting signal handlers prior to calling the hook.
- libalpm uses GPGME for signature checking. GPGME uses pipes to communicate with external processes. When GPGME is initialized it sets SIGPIPE to be ignored, so that it can gracefully handle EPIPE rather than have the entire application die.

This bug is to track fix into pacman, and when I can remove the workaround in dkms.
