yeah, I know, but I was not asking for the list of failing tests, but a
list with *only* the hanging tests.

I was just curious, if you don't have this, nevermind.

Btw, can you add a commit with the instructions and the script? Easier
to find then a mail in this thread... :)

this list also is the list of hanging tests. As

Oh, good.

well, only starting at one point in the patchset where you disable smb1,
but at the end of the patchset all tests would be running again. My idea
was, that this would aid in having clear, simple, reviewable, CIable

Let me know if you need help. 4a7ec5b7604 is an example how to add a s3
env. Just remember to also update get_realm_ip_mappings() when adding
new s4 DC envs.
