This now works!

Looking at the bootchart, appears that system is spending about 5
seconds elapsed time doing a "find".

I think I tracked this down to the following snippet from /etc/rc.d/rc.sysinit:

# Clean up /var.
rm -rf /var/lock/cvs/* /var/run/screen/*
find /var/lock /var/run ! -type d -exec rm -f {} \;
rm -f /var/lib/rpm/__db* &> /dev/null
rm -f /var/gdm/.gdmfifo &> /dev/null

The problem is, I seem to have over 325 entries in /var/run/gdm of the form:

[root at tlondon gdm]# ls |wc
    326     326    6520

What should be cleaning these up?
