As is common for scripts to look for home directory just by reading $HOME environment variable, our first approach was to not change user database and modify the $HOME variable to a temporary directory when spawning the task command without creating a new user. This way, we could clobber the task just by removing the $HOME directory. This approach worked for most tests but xpcshell. Particularly, it checks if $HOME matches user database, making this test to fail. As we may not be allowed to change even the current user home directory, we fix this by using the user's true home directory. This implies that we only need to create a temporary directory if we create a new user to run the task, otherwise it is not necessary. We also need to explicitly set the correct owner of the context file. https://github.com/taskcluster/taskcluster-worker/commit/8ce5497bfd9baf8faa28a97e9588b403f29009e3 Merge pull request #161 from walac/master Bug 1339196: Make $HOME and os/user.Lookup().HomeDir equal. r=jonasfj
