--- Comment #2 from Ian Lance Taylor <ian at airs dot com> --- The relevant failures are: --- FAIL: TestCloneNEWUSERAndRemapNoRootDisableSetgroups (0.00s) exec_linux_test.go:74: Cmd failed with err fork/exec /usr/bin/whoami: in valid argument, output: --- FAIL: TestCloneNEWUSERAndRemapNoRootSetgroupsEnableSetgroups (0.00s) exec_linux_test.go:114: Unprivileged gid_map rewriting with GidMappingsE nableSetgroups must fail --- FAIL: TestEmptyCredGroupsDisableSetgroups (0.00s) exec_linux_test.go:122: fork/exec /usr/bin/whoami: invalid argument This means that your system doesn't support some kinds of user namespace features. The test should arrange to not fail when those features are not supported.
