In the default Buildroot target skeleton, /var/log is a symbolic link
to /tmp, and /tmp is mounted as a tmpfs (the contents of the filesystem
are stored into memory).

So with the default Buildroot configuration, the contents of /var/log
(and many other /var directories) are lost when you reboot.

Cheers,

Thomas
