In both cases it is doing the wrong thing IMO; a circular buffer would
be the right thing for a default.

Right now it's logging to tmpfs, which takes up ram, which more scarce than
disk. You can easily remove /var/log/journal in ROOTFS_POSTPROCESS_CMD to
make it log to tmpfs again.

I understand however I think that write the log to the disk by default
is wrong. We can do it by machine basis or other type of override by
by default we ought to avoid writting to disk.

And that's why patch 1/3 enables xz compression :)

I'd prefer if journal could default to use a buffer or something
similar instead of writting to disk as we ought to be careful about
space in embedded devices, in general.
