Bug#403833: gpg-agent: enhance --write-env-file to append $HOST to filename

[Jari Aalto]

Package: gnupg-agent
Version: 2.0.0-5.2
Severity: minor

Please enhance the --write-env-file to append current host to the filename:

  now     : $HOME/.gpg-agent-info     
  proposed: $HOME/.gpg-agent-info-<hostname>

The motivation is that hosts usually use NFS mounted home directories and
reading the current $HOME/.gpg-agent-info will not work in another host.


        Host X             +----- host A
                           |
        /home           ---+----- Host B
                           |
                           +----- Host C

If user log into all hosts:

   ssh user at hostA                           
   ssh user at hostB                           
   ssh user at hostC

The initialization code in ~/.profile could work if  --write-env-file wrote
host specific files:

   $HOME/.gpg-agent-info-hostA   
   $HOME/.gpg-agent-info-hostB
   $HOME/.gpg-agent-info-hostC

It would be even better if the host portion used FDQN instead of the
hostname(1).
