USB booting :: Frugal and KNOPPIX filesystem

I'm new to DSL but what I have seen so far - cool!!

Still I have a problem:

I made a frugal Install to hda1. Everything is working fine-so far...

On the machine I need a special device driver which normally installs in /usr/local/lib.

As I understand all *.tar.gz archives that reside in the "restore-drive" (hda1 in my case) are extracted at boot time.

So I packed the driver into (let's say) driver.tar.gz.
When booting the archive doesn't extract because /usr/local (actually the whole KNOPPIX-fs) is read-only.
Can I change that? I Know ir is a RAMDISK "fake" filesystem but that doesn't mean it has to be read-only (or does it?)

Thanks for yout help!

and another thing - could be related to that problem:
/dev/hda1 gets mounted in /cdrom.
No entry in the fstab for that, but in /etc/mtab:

/dev/hda1 /cdrom ext2 rw 0 0

I can't even umount the darn /dev/hda1 (device is busy)

I'm lost here...

This is normal behavior for a frugal install.

If you want your driver.tar.gz to be able to add files to /usr/local

Then rename the file into driver.dsl

When the dsl installer sees the *.dsl extension, it will create a writable /usr filesystem and then extract the files into it.
