Rename puavo-ltsp-mount-nfs-home to puavo-ltsp-init-nfs
Make pam_krb5 ignore ~/.k5login files so that they do not generate unnecessary file lookups if user home dir does not exist yet on the NFS server.
Do not allow logins using ssh keys through the ltspsshd port as we want only gssapi based logins. Stops ltspsshd from reading ~/.ssh/authorized_keys2 files through NFS which fails before user kerberos credentials are in place.
