I believe a default variant is requested unless the first command to
install the port has variants explicitly mentioned but it is not requested
in the context of a user because the user can probably be unaware of
But again, as you said, there can be different default variants, storing
the original defaults can result in confusion between what originally was
default (they should not become requested) and what is the current default?
So, I think we should NOT treat the default as requested. Replicating the
actual user commands is the most ideal thing to do.
A confusion could have been here: `port install port_name` and `port
install port_name +default`. Both will install default but it's not
requested in first case while requested in second case. The second one
should get listed as requested in db and hence, not create any problem
> Should we include variants the user did not supply to the port install
I didn't get it. Either the variants are default or they were requested,
both will be present in the stack. How can we get the variants which the
user never supplied? Are you trying to hint at the difference in the port
installed at the first run and the variants installed later on?
Also, I need your help in a technical detail. I'll try to push in some time
and get back to you if you're free.
