Hi William

You're right that root.img is created with a fixed capacity, and that 
sometimes this can be an issue
However I am surprised because the logs, at least as far as /var/log is 
concerned, should go in a directory that is physically located under 
/plc/data, i.e. *not* in root.img.
So provided that we are talking about /var/log/, it seems that your 
myplc does not behave as expected to this respect

It would help if you could post the output of
# chroot /plc/root df /var/log
# ls -ld /plc/root/var/log
# ls -ld /plc/data/var/log

What you should see from the chroot:
the /data directory is mounted on /plc/data, which is on your hard drive 
outside of root.img
/var/log should be a link to /data/var/log
