Description Jerry James 2016-11-26 03:59:04 UTC 
Description of problem:
Running useradd creates a file named /1.  The file is 0 bytes long and is owned by root:root.

Version-Release number of selected component (if applicable):
shadow-utils-4.2.1-11.fc25.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Run "useradd test" from the command line
2.
3.

Actual results:
If SELinux is in enforcing mode, you will get an SELinux warning about creating the file.  Otherwise, it is created silently.

Expected results:
No weird files created in the root directory.

Strange but I wasn't able to reproduce the issue on fully updated Fedora 25. Even more strangely - I originally had the /1 file present in the filesystem but after deleting it it did not reappear after the 'useradd test' and there also weren't any related messages from the SELinux in audit log.
