[Zope] DirectoryStorage & ZEO... how?

[sean.upton@uniontrib.com]

"1" in "-S 1=" is just the storage name you want to pass to ZEO clients. If
you pass more than one storage to clients (say, you use DBTab on the ZEO
clients), you might want to choose more descriptive names (like
'main_storage','foo_storage',etc) on both ends, but that's your choice.

ok, that's what i thought the -S syntax was, though i wasn't sure
about the "1="

aha! for some daft reason i thought that custom_zodb was a magic name.
i was wondering how on earth to combine the client and server setup in
one custom_zodb... the answer is, "don't" :)

eek!  thanks to your message i spent only a few minutes fiddling with
permissions.  well, actually "find . -exec chown zope {} \;" took quite
a long time in my directorystorage ;-)

you rock!

i'm editing your message into a doc to send to Toby which i hope he'll
consider including with the DirectoryStorage docs.
