I think I misposted my question. It should've been:
Will the post-commit trigger execute for all commands
that I may care about (eg mkdir, cp, import)? Upon
import, the trigger should create the necessary LATEST
and 0 branch and label, respectively.
The trigger shouldn't need a working directory since
all it's doing is directly creating copies in the
repository. Or am I missing something?

I'll double check the docs to see how triggers
interact with the transactions. Since Subversion is
using a database, I'd think things should work as
expected (eg a transaction can't lock itself out and
everything occurs within the same transaction), but
you never know.

I hadn't thought of this (that the repository revision
increments for each branch/label created) but it
shouldn't really matter, anyway.
Thanks,
