Well,

      export CONVERT=true ; fai -vN -s file:///srv/fai/config/ softupdate

is not supposed to be run twice ... so there might be other failures
too.  But perhaps it is a good idea to make sure all actions are
idempotent also for CONVERT=true to make the setup even more stable.

I'll keep that in mind.

Thanks,
