PCMCIA card service is started as deamon on the backgroung. Thus the
script run after PCMCIA script and PCMCIA script itsself run
concurrently.
If you have some initialization script which you need to run after
bringing up PCMCIA NIC, there are 2 ways.
1) Run those scripts from PCMCIA network script. (Right way)
/etc/pcmcia/network.opts needs to define shell functions:
start_fn() {.....}
stop_fn {.....}
2) Run them after PCMCIA, optionally put some "sleep" to avoid race
condition.
You are taking 2nd option. Depending on actual set up you may encounter
race condition but your delayed start approach should stay as is most
likely. Even if it breaks, you can move it again.
Cheers :o)
