Comment:

 The default in MacPorts 2.10 will be to store port images as directories
 when they are stored on an APFS filesystem. This will probably cause
 inactive ports to use a little more space, since the files are only
 individually compressed with HFS compression rather than being packed into
 a tar file and bzipped. But because clonefile() is used when activating
 them, activating will use almost no extra space, will be far faster, and
 will cause far less SSD wear. Existing archives are only extracted when
 the associated port is activated, so there won't be a sudden increase in
 disk usage.

 I added code to mpbb to create an archive in the gather-archives step if
 there isn't one in the port image location, so the default setting should
 actually be fine. We can revisit this if there turn out to be unforeseen
 issues.
