Question 1: I thought I had to create directories manually when copying my own destroot or pre- or post- destroot phases. If not, can it simply be omitted for the file specified in the MacPorts guide under "MacPorts File Hierarchy". That is the mtree, correct?
I think I create directories in destroot for a lot of ports, and I thought others did too so I'm confused.
Don't worry, I've just discovered that by mistake, I haven't created an mtree directory and xinstall didn't complain. I think they are created before the destroot stage and that these that remain empty after are deleted in destroot_finish.
Okay, so the rule must be that you don't need to create directories manaually to put files in top-level mtree directories for destroot or post-destroot phases, otherwise yes.

There's the ${prefix}/etc/macports/prefix.mtree file and whatever is listed there is created by MacPorts itself during the pre-destroot stage as the installation bed for a destrooting port (destroot_start proc in base/src/port1.0/portdestroot.tcl [1]). Once the destroot stage is done, whatever directory in the destroot that's void of any files (that is, the destrooting port didn't place anything in them) gets pruned during the post-destroot closing stage. Therefore, anything else that's not in the default mtree needs to be created manually and anything you intend to keep for installation even if empty has to be safeguarded through a destroot.keepdirs clause.
HTH! Ping me if not ;-)
Nice. I got it. More fodder for the new guide. Mark
