Puppet

If ENV[‘HOME’] is not set, then the run mode code will call Etc.getpwuid(Process.uid).dir which doesn’t work on Windows because there is no Process.uid and the ‘etc’ module is not available.

Normally this code path is not executed, because Ruby always sets the HOME environment variable based on the HOMEDRIVE and HOMEPATH environment variables. But I suspect that the recent change to unsetting the HOME (and other POSIX) environment variables in a different test case. This would explain why this failure only occurs in master and not 2.7.x.
