fsck has logic to force a full preening fsck of '/', permitting background file system fsck only for non-root file systems. For the past few weeks, I've been wondering why it takes *so* *long* to fsck the root file system of one of my boxes at work, only to find out that the reason is that it's running a non-background fsck on /dev/da1s1a, which is an 'a' partition, but not the root file system (/dev/da0s1a). It successfully uses bgfsck on /var and /usr, but not /local0. So it sounds like the logic in fsck is simply guessing that any 'a' partition needs a foreground fsck. This might be a problem if you wanted to background fsck a multi-terabyte /bigpartition for exactly the reason bgfsck was introduced. :-) Has anyone else run into this, or perhaps want to fix it?
