Description Adam Williamson 2013-03-20 00:13:22 UTC
Description of problem:
Occurs on boot of a Fedora 19 live image built from current repositories.
SELinux is preventing /usr/sbin/useradd from 'setattr' accesses on the file passwd-.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that useradd should be allowed setattr access on the passwd- file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep useradd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Adam Williamson 2013-03-20 00:13:36 UTC
Final blocker: "In most cases, there must be no SELinux 'AVC: denied' messages or abrt crash notifications on initial boot and subsequent login"

Comment 2 Adam Williamson 2013-03-20 00:15:11 UTC
There's also a "/usr/sbin/useradd write passwd-".
