For various reasons I can't reformat/repartition the hard disk on the laptop I am using (mainly there's just not enough room on its 64GB SSD) so I am using backtrace via a bootable USB stick.

Backtrace doesn't seem to support the build in wifi which is a RTL8192CE. I downloaded the linux drivers from realteks website and put it on the fat32 partition of the thumb drive (mounted in backtrace on /media/cdrom0) and it was able to 'make' then 'make install' without errors, however it requires a reboot to work. Naturally a reboot clears any and all changes made

That said, is there any way I can merge the changes made on to the USB stick? Something simple please, I know a bit about linux but I'm by no means an expert.

The RTL8192CE driver can be found here:
