Not really, but the frontend writes some files in the /home/user/.mythtv 
folder (themes icons for example). May be your NUC was set up rw when 
you first started the frontend.

On the other hand, some file systems are "friendlier" to flash memory 
than ext4 (JFFS2, F2FS and others), and converting to them seems very easy:
