I think this is a bit too complicated / wordy. When there are sensible
defaults we add those to the init script and just allow an
/etc/default/<pkg> to override it for special setups, so I've dropped
the etc.default.tpm2-abrmd.
The same for S30devtpmperms - I have simply added:
chown tss:tss /dev/tpm[0-9]* && chmod 600 /dev/tpm*
To check_device() in S80tpm2-abrmd and dropped S30devtpmperms.
Committed with these changes, thanks.
