I am trying to extract a tar file three different once for my PDA and this is the error.

I am guessing there is something wrong with the files or am I doing something wrong. I have tried to extract 3 different all give me the same output.

What filesystem do you use on that device?

Not all the file systems around support device nodes. That's probably the problem.

This is the kernel and file structure or a pda Ipaq hx4700 Angstrom GPE

For what I can see from a quick Google, it uses a distro that's called Angstrom. I have no idea what fs does Angstrom use. Are you following a wiki or manual that we can review to know what are you trying to do?

If so, please, point us in that direction.

Can you run the "mount" command without parameters and paste the output here? That will let us know what file systems is it using, and that way we can discard a problem with that.

Why are you trying to move /dev filesystem somewhere else? It's dynamically created, and valid for only one particular computer. Use tar with -exclude to omite /dev (and /proc) filesystem.

And your system is right. Only superuser can run mknod.

I am not trying to move it I am trying to install it. I had my Ipaq working with the SDG Bootloader. Angstrom doesn't support SDG Everytime I got the PDA how I wanted it and I would loose the task bar, it would not reboot and so on. So I am trying to install it with Haret so install is as follows. A fat16 partition with Haret, startup.txt, and the kernel then a EXT2 partition with the root file system. I get the error when I try to extract the root file system tar.gz either on my pc or SD/CF I am using the wiki or haret as well as andstrom GPE
