Oh, now I'm confused, both syntaxes do something, and it's not clear to me what 
the difference is.

Hello,

If I am not wrong,

apt purge --autoremove $SOMEPACKAGE
  will purge SOMEPACKAGE package and automatically remove its dependencies that 
are not needed anymore. But leaving intacts the configuration files of these 
dependencies

while

apt autoremove --purge
  or
apt autopurge
  will purge (including configuration files) all unnecessary packages (packages 
marked as installed automatically as dependencies of a package that is not 
installed anymore)


Ah yeah that makes sense, I've also learned about autopurge, can use this to 
remove unused kernels since dkms leaves bits and pieces behind.
