Is there an easy way to copy all attributes from layer 2 of a vector points map to layer one (which doesn’t currently exist - is will need to be created)?
Alternatively, maybe all I really need is a way to rename layer 2 to layer 1 while keeping all attributes intact.
Background: I need to move all the attributes to layer 1 in my point map in order to patch vector maps together with v.patch.
Thanks,

You need to distinguish between category values of the vector points and attribute tables linked to a particular layer.
You can change the layer number of category values from layer 2 to layer 1 with
v.category option=chlayer layer=2,1
Now you need to reconnect the attribute table from layer 2 to layer 1 with v.db.connect
