pdksh Shells Path Incorrectly Set at Install in Red Hat Enterprise Linux 5

Issue

• When installing pdksh, binary gets installed in /bin/pdksh:

# rpm -ql pdksh | grep pdksh
/bin/pdksh
/usr/share/doc/pdksh-5.2.14
/usr/share/doc/pdksh-5.2.14/BUG-REPORTS
/usr/share/doc/pdksh-5.2.14/LEGAL
/usr/share/doc/pdksh-5.2.14/NEWS
/usr/share/doc/pdksh-5.2.14/NOTES
/usr/share/doc/pdksh-5.2.14/PROJECTS
/usr/share/doc/pdksh-5.2.14/README
/usr/share/doc/pdksh-5.2.14/etc
/usr/share/doc/pdksh-5.2.14/etc/ksh.kshrc
/usr/share/doc/pdksh-5.2.14/etc/profile
/usr/share/doc/pdksh-5.2.14/etc/sys_config.sh
/usr/share/man/man1/pdksh.1.gz

• Path to shell in /etc/shells gets added as /usr/bin/pdksh:

# cat /etc/shells | grep pdksh
/usr/bin/pdksh

• Post install script from the RPM is what adds the path as /usr/bin/pdksh:

[root@dsirrine-ds-test ~]# rpm -q --scripts pdksh
postinstall scriptlet (using /bin/sh):
if [ ! -f /etc/shells ]; then
     echo "/bin/ksh" > /etc/shells
else
     if ! grep -q '^/bin/ksh$' /etc/shells ; then
          echo "/bin/ksh" >> /etc/shells
     fi
fi
if ! grep -q '^/usr/bin/ksh$' /etc/shells ; then
     echo "/usr/bin/ksh" >> /etc/shells
fi
if ! grep -q '^/usr/bin/pdksh$' /etc/shells ; then
     echo "/usr/bin/pdksh" >> /etc/shells
fi
