[Voyage-linux] Problems unmounting with voyage.update

[Erik van Linstee]

Hi,

I recently noticed that if I create a new CF using voyage.update, at the 
end of the process the script complains that /mnt/cf/dev and /mnt/cf 
can't be unmounted.
If I then unmount them manually, there is no problem.

I traced the problem to setboot.sh, where an attempt is made to unmount 
/mnt/cf/dev, right after GRUB has been set up. If I add a sleep 1 before 
the unmount, there is no problem.

Apparently there is a timing problem, which could in my case be due to 
the CF being mounted in a USB card-reader. I have reproduced the same 
behaviour on more than one machine, with different card readers (same 
make though).

It seems that the failure to unmount does not result in an unfinished 
CF. Apparently the installation script is done anyway. But it might be 
smart to fix it, just to make sure people do not get confused by it.
