I added some code to remount /boot or / read only and then back to read
write (/boot or / depending on if /boot is a seperate partition) and
if /boot is a seperate partition it can be remounted ro and back to rw
just fine without any problems and then it all works and grub installs
fine but with / I still get the same problem that Filesystem in use.

Why wouldn't I be able to remount / ro ? Wouldn't that be because
someone is holding a file on / open in write mode?
