Comment:

 I'm aware there are several tickets now in which ports are forbidden by
 MacPorts 2's privilege dropping code from writing and sometimes reading
 items in the user's actual home directory; in these cases we have been
 modifying the port to set HOME to something inside workpath.

 I'm not sure why in some cases like #30289 it seems to know what the
 macports user's home directory is, and in other cases it doesn't. As I
 said I wasn't aware of MacPorts base actually setting HOME to anything at
 this time. Perhaps it would be good for MacPorts base to create a
 directory "${workpath}/home" for every port install and set HOME to that,
 since that's what we already do manually in some ports (clisp (#31257),
 parallel (r86242)).

 Several ports have actually used this in-workpath HOME env var for a lot
 longer than the privilege dropping code has existed (kmymoney (#24433),
 the kde and koffice ports (r27011), plplot (r22893), scribus (r19058)) so
 it may even be a good idea to standardize this for other reasons.
