I think svscanboot is a service of daemontools which for some reason you have used in place of xinetd. You must be running qmail as the mta I assume.
This error is not something to disregard, you lkely have services that are not runnng that should be as a result. You need to provide more detail though.
Is this error after you installed daemontools?
try this:In boot.inittab, /command/svscanboot is changed to /usr/sbin/svscanboot.
does it look right?
