Re: [Ltib] USB automount and auto-run on LTIB?

[Stuart Hughes]

Hi Kevin,

udev should be selectable in the normal config, run;

$ ./ltib --configure

and then navigate to; Package list / device nodes and pres enter, you
should see these options:

 ( ) static device files
 ( ) use mdev
 (X) udev
 ( ) devfsd dynamic device file daemon
 ( ) don't install any device files/nodes

Select udev if it's not already selected (for many boards this is the
default)

Regards, Stuart
