Ummm, not sure :-) I do know that it applies for loading of driver modules.
As I understand it, if you have an LTmodem, and that on "modprobe lt_modem"
it creates the device file /dev/tts/LT0, if you have the following line in
modules.conf or modprobe.conf:
alias /dev/modem lt_serial
then if your ppp dial-up program attempts to read /dev/modem, the system loads
the lt_modem module, and if successful, then creates the sym-link
from /dev/modem to the device file created by the driver. When the modules
gets removed, (i.e. ppp disconnects), then the sym-links get removed.
Take a look at the man pages for modules.conf and modprobe.conf for more
details.
John.
