The test/suite/hook_disagg.fail list has a number of failures that happen when running test_prepare*.py files with the disagg hook.  These failures should be triaged - made into tickets and assigned to appropriate teams.  When a ticket is fixed, the corresponding line(s) in hook_disagg.fail should be removed.  If a test does not apply to disagg, a line like:

@wttest.skip_for_hook("disagg", "...reason why we're skipping...") 

should be added to the test, and the line in hook_disagg.fail should be removed.

To run a test with the disagg hook, do:

cd build
python3 ../test/suite/run.py -v 2 --hook disagg test_foo22.py
