Addition of selinux users causes "Multiple same specifications" warnings during startup

[Radha Venkatesh (radvenka)]

Dan,

I have created SeLinux users which can take on roles of system_r and
sysadm_r and tied them the Linux users created (though they are
nologin). This is needed so that these linux users can execute
applications in our product taking on system_r or sysadm_r roles.

Thanks,
Radha.

Then why are you assigning user context to the accounts.  genhomedircon
must have a bug in that it is ignoring the shell if the user has an
assigned seusers label.
