/var/log is defined in /etc/rwtab as a tmpfs.  On XO-1, having many
short writes to text files -- as happens with logs -- grows the JFFS2
node tree in a way that slows down boot and generally hurts I/O
responsiveness, so we don't do that.

I suggest putting your new logs somewhere else.  You can look at
/etc/rwtab to see where is available.
