You need to use a loopback device in order to mount an image as a filesystem. Assuming
that your kernel has been built to support the loop device (most distros do this by default,
either built into the kernel or as a module - that doesn't matter for what you do, though),
then you can check to see that you have devices /dev/loopn where n is usually 0 through
some larger number.
If you have in your current working directory the unzipped ramdisk image (eg you've taken
ramdisk.gz from Brian's splitnslu2 program and unzipped it with gunzip -N ramdisk.gz),
then you can mount it with:
mount -t ext2 -o loop ramdisk test
(you need to be root to do this).
Now, cd into test and you are in your ramdisk file system. Make whatever mods you want,
then go back to the original working dir.
gzip -9 -f ramdisk
will zip it back into ramdisk.gz, and then you can use splitnslu to put the image back into
a new flash image.
Apparently, under MacOSX (which I am using) you can just click on a disk image in the
finder and it will mount automagically - if the filesystem is supported by the Mac, which
ext2 is not.
