The root partition is probably checked in the foreground for safety reasons, since the root partition is so critical to everything on the server. Personally I don't use or trust background fscks -- when a server comes back up after a crash, I'd rather it just finish the fsck before coming up live, since the fsck does slow the server down noticably (and if it was an already busy web server, this can be a problem). There's also the matter of serious problems with background fscks, with open PRs: http://www.freebsd.org/cgi/query-pr.cgi?pr=3Dkern/53137 http://www.freebsd.org/cgi/query-pr.cgi?pr=3Dkern/86423 and the less serious (since it is about UFS1): http://www.freebsd.org/cgi/query-pr.cgi?pr=3Dkern/84589
