Sorry this is late, I put it in drafts and forgot about it.  Important none 
the less.

The system is behaving exactly as it should be.  Your kludge isn't totally 
off.  But it may have its problems if you are running any network services 
that start prior to your little script running at S99 - rc.local.

The best bet would be to 'tune' the order in which services come up for your 
particular runlevel.

For your purposes you would want pcmcia services to come up before networking 
comes up.  This can be useful with a laptop that is statically assigned an 

With my laptops I prefer the to bring up a specific networking configuration 
depending on what location I am at so I don't mind the default behavior. 

System V init scripts allow you to tune when and in what order services come 
up for a defined runlevel.   S for start and an integer S2, S22, S45, etc. the 
system will bring services up in numerical order.

On a stock RH box pcmcia comes up at S24, networking comes up at S10... so you 
see a gap there between the two, we have 5 or so services starting up 
in between the two we want.

No problem.  Let's start pcmcia prior to networking coming up.... say S8 or 

You have two choices, either change the symbolic link in your runlevel 
directories from an S24 to an S8 OR edit the init script for pcmcia... there 
is a commented sequence of numbers at the top of each init script 
in /etc/rc.d/init.d/ , if you take peek you will see a sequence like so... 
note the chkconfig line.

# rc.pcmcia 1.39 2001/10/04 12:30:05 (David Hinds)
# This is designed to work in BSD as well as SysV init setups.  See
# the HOWTO for customization instructions.
# Tags for Red Hat init configuration tools
# chkconfig: 2345 24 96

This tells the chkconfig command to turn pcmcia on at S24 in runlevels 2345 
and turn it off at K96 in runlevels 0 and 6.  Change the 24 to an 8 or 
whatever you choose.  YES, chkconfig looks to this line when you use the 
command from the command line.

Then re-run chkconfig on pcmcia;

chkconfig pcmcia off
chkconfgi pcmcia on

boom, next time the machine comes up pcmcia services comes up before 
networking comes up.
