When debugging don't enable daemonizing, instead run it in foreground
to see what messages, if any, it prints.

But this is, with a very good chance, #625571 - migration
fails on 32bit userspace always.  That bug is finally fixed,
after more than 2 years, and is pending upload after we will
sort out other, more important issues.

Again, this is a very bad idea to run it in backrgound when
debugging.  It's impossible to tell what exactly it is doing
this way.
