from

Code:
if [ $? = 0 ]; then
  umount $MP 2> /dev/null
fi
  RC=$?
else
  # it is not mounted
  RC=0
fi
to:
Code:
if [ $? = 0 ]; then
  if [ "$MP" != "/" ] ; then umount $MP 2> /dev/null ; fi
  RC=$?
else
  # it is not mounted
  RC=0
fi

2. Can anyone confirm the best method to edit the boot menu, eg set it to boot from external card by default (and remove option to boot from internal 2gb memory on n810)

As a side note, is the boot from usb hard drive option used for anything?

3. Just for future info, if i wanted to re-flash the external card with the basic installation i have saved on the internal flash, which steps do i take to do that?

1. Yes. [If the italics are a problem, t's easier to read the code above here.] (As an aside, my original file did not include the first fi and, initially, I omitted it also from the changes I made. That didn't work. Then I added the "; fi" and it did.) (Also, if someone wants to edit that file in emelfm2, you can do it only if you launch emelfm2 as root from Xterm.)

2. I think what you want is this. I'm not sure if you want immc1 or immc2.

3. I think I'm not understanding your question. What you're asking seems to me to be what you just did; if you follow Post #1 and don't flash the OS, you end up, on the external card, with whatever you had in the internal flash. The problem along these lines is what do you do if you want to update the OS by flashing -- you'll have to wipe out whatever changes you made since cloning and rebuild from backups.

Also, thanks, Stal, for the permanent home for the zipped cloning files. I downloaded it as a test and it was slow but worked. I'll be updating Post #1 or #2 with the new URL.
