[ELDK] How to mount sysfs ?

[J.Hwan.Kim]

Hi, everyone

I'm using ELDK4.2.
But Kernel does not have /sys file system.
My .config file tells CONFIG_SYSFS = y.
Someone tell me I should mount the sysfs in my system.
What file must I modify in my root file system?
In ELDK, there is no file such as  /etc/fstab or /etc/mtab.

Thanks in advance.
Best Regards,
