-## Notes
-
-- problem was that the extension defaults to prod mounttable and assumes
- blessings minted by prod identity server, but local mount table and syncbased
- run with local credentials and do not include dev.v.io in trusted roots.
-
-- one solution is to configure the extension with local identityd,
- identitydBlessingUrl, and namespaceRoot, but this requires running Chrome as
- follows and manually editing the Chrome extension options on each restart.
-
- /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --ignore-certificate-errors --user-data-dir=/tmp/foo
-
-- to avoid manually editing options, we could build the Chrome extension as part
- of "make serve" - that's what our tests do. ew.
-
-- alternatively, we can include dev.v.io in our local mount table and
- syncbased's trusted root sets, and have their "root dirs" allow access to
- anyone. secure b/c these services are only accessible on localhost. for this
- to work, we'd need to configure the webapp to talk to the local mount table.
-
-- even simpler, we could bypass mount table completely and have the webapp talk
- directly to local syncbased. in addition, instead of overriding the trusted
- root set, we can run the local syncbased with a dev.v.io blessing by using
- seekblessings. (both here and above, all extension opts are left untouched,
- and dev.v.io blessings are used.)
