…MIPS The value of ENOSYS differs between MIPS and non-MIPS architectures. While this is not problematic for the embedded seccomp profile, it prevents the profile from being saved as a portable JSON file that can be used for both architectures. To work around this situation, we include conditional rules for both arches. and hard-code the value for ENOSYS in both.

Failure on Windows 2022 looks like a flaky (tracked in #42612); |

discussing this change, and (see opencontainers/runtime-spec#1087), perhaps the better solution is to fix the OCI spec to take a string instead of a number for the signal. This feature hasn't shipped yet in the OCI spec, so we can still fix it. |
