One would think that after restoration, the machine would be in a state sufficiently similar to the one it was in at backup time, but for our purposes, it is not, specifically with regard to user accounts.

Right, I'm using 10.12, but I assume the problem exists in earlier versions as well. I may have written about the problem before, but if so, I couldn't find it, and don't remember what conclusions we may have reached.

Not always, because many ports use local variables when setting the home directory, so you then have to find the place in the Portfile where that local variable is set. And also, many ports split the add_users invocation over multiple lines, such that the line that sets the home directory might not be on the same line that includes the string "add_users".
