init: Replace stupid system serial by uuid
init: Replace stupid system serial by uuid

On some motherboard like Tyan or Supermicro, the system serial number is always
the same like '000000' or '123456789'.

On the server, it results in a series of similar log filename.

This patch simply replace the invalid serial number by the uuid which is usually
filled.

As an example:
    /var/lib/edeploy/logs/Supermicro-X8SIL-0123456789.log.gz
is now:
    /var/lib/edeploy/logs/Supermicro-X8SIL-49434D53_0200_9003_2500_03902500E9B6.log.gz
