Issue

/etc/bashrc change causes umask to not be set.

Curstomers relying on this initial statement in /etc/bashrc (from setup-2.5.58-7.el5 or earlier) to set the umask may experience changes with setup-2.5.58-9.el5 provided by RHEL 5.8.

if [ $UID -gt 99 ] && [ "`id -gn`" = "`id -un`" ]; then
    umask 002
else
    umask 022
fi

The above code was moved into a test later in the /etc/bashrc script to only execute if the the shell is not a login-shell. This was done as part of http://rhn.redhat.com/errata/RHBA-2012-0198.html in reaction to BZ# 608987, to ensure that /etc/bashrc does not over-ride any settings made in /etc/profile and /etc/profile.d/*.sh scripts.
