[New-bugs-announce] [issue32601] PosixPathTest.test_expanduser fails in NixOS build sandbox

[Anders Kaseorg]

New submission from Anders Kaseorg <andersk at mit.edu>:

PosixPathTest.test_expanduser fails in the NixOS build sandbox, where every user has home directory /, so it falls off the end of the for pwdent in pwd.getpwall() loop.
