LGTM, you need to rebase once #27234 is merged to unblock CI.

Ok it still flaked, I added the info to microsoft/WSL#13301 (comment)

See the comment there with how the tests overwrite USERPROFILE so I wonder if this setting was actually read or must written as part of the test suite setup to take effect.

See the comment there with how the tests overwrite USERPROFILE so I wonder if this setting was actually read or must written as part of the test suite setup to take effect.

I suspect that the problem was that we created the wslconfig file if $env:CI -eq "true". But that variable doesn't exist, the variable to test is $env:CIRRUS_CI.

I am not sure how that works with the USERPROFILE override in the tests as well though

However I just realized that our tests do some "mocking" as the test overwrites USERPROFILE and some other env vars with a temp dir to avoid cluttering the actual user home if it is run locally. So I wonder if this actually worked or we need to add the config to the new USERPROFILE for each test case.

Could be that we actually have to create the file in the BeforeEach() where we setup the temp home as well as I don't know how wsl reads the file.

Anyhow seems like test passed this time but this is no solid indicator though its general flakiness, we should keep pressing rerun a couple of times https://cirrus-ci.com/task/5074728311848960 to see if we can it to fail still

[Luap99]

Ok it still failed after the third rerun https://cirrus-ci.com/task/6196427237359616

[Luap99]

Mind adding the config write into the go test code where we update USERPROFILE to see if that changes things?

[l0rd]

I have updated the BeforeEach(). Let's see if this work better. For the record yesterday I was able to run the e2e suite with a .wslconfig in my $USERPROFILE to specify a custom kernel. That was for testing nftables support and it actually worked (test were passing so the new kernel was used). But I am not sure if the properties wsl2.kernelBootTimeout (undocumented) and wsl2.kernel are evaluated at the same time.

Tests are still barking, but the code LGTM
