Thank you very much!
I will see how I can apply this, in a single sh script with the 
unattended key generation as well. The thing is I "feed" the private key 
material to gnupg for generation, the key is not generated randomly.

Isn't it wise to add a "Subkey-Expire-Date:" param that will map to 
pSUBKEYEXPIRE (I can see there is a pSUBKEYEXPIRE from browsing the 
code)? That will only touch the subkey itself, without caring about the 
primary key? Or it doesn't work like this?
