Hotplug is the buggy work-in-progress standard mechanism of the future
whereas cardmgr is the debugged bloated obsolete mechanism of the past.
Take your pick.

Look at the ifupdown package:


Even if you don't want to install the package, the README file may
be helpful to you.

It's a Debian issue.  The hotplug and ifupdown maintainers are inactive.
However, I don't know of any other distros that have better support for
automatic dynamic configuration of laptops.  Do you?

I should make one thing clear.  If you have PCMCIA cards then you always
need cardmgr per se.  When you put an "exit 0" at the top of
/etc/pcmcia/network you only disable the interface configuration code.
However, cardmgr is still used to load drivers, to control the sockets,
to beep, etc.
