Re: [PATCH RFC] module-setup.sh: install usb serial driver for ttyUSB0

Hi, Freeman

The patch just auto detect and install drivers.

But I think I'm fine with using extra_modules in kdump.conf though.

Hi Dave,

You once sent a patch to install usb serial driver for ttyUSB0 in 
dracut-module-setup:

https://lists.fedoraproject.org/archives/list/[e-mail]/...

Actually, we can achieve this without any patch by a delicate configuration.

One can use extra_modules configuration entry in /etc/kdump.conf to add 
USB serial drivers, e.g:

extra_modules pl2303

And enable the console by making sure 'console=ttyUSB0' is contained 
in kdump kernel cmdline.
You may want to take a loot at KDUMP_COMMANDLINE_APPEND in 
/etc/sysconf/kdump.conf
if current cmdline includes no 'console=ttyUSB0'.

I suppose we should let the configuration do the job. What do you think?

All the best!
Freeman
