Nice summary.

Any comments on using commit triggers, svn:ignore, and keyword
expansion?

eg if log files are going to co exist with the checkout do you
need to ignore them? where is your ignore file? how do you trigger
an update to a staging (or live) checkout with commit, or commit
to a specific (log) file in the repo (hook script)? I'm thinking
for desktop checkout htdoc mods and/or staging/production restarts
with httpd.conf &c checkin.  I miss "local keyword expansion"
from cvs, is there any way to enable svn keyword expansion for an
entire repo, or does it need setting per file? how do you manage
that?

BTW I see your doc is missing the NetBSD section,

cd /usr/pkgsrc/devel/subversion && make clean install

that seems to work anywhere pkgsrc is in use.
