The bottom line: There is no problem even if flashdrives/cameras etc
are in fstab but not present- you simply get the error logged

Well, there is a definite problem in my case (Debian unstable on i386).

Error code 1 on fsck gets an error logged, but doesn't stop the boot
process.

Upgrading dosfstools past 3.0.1 caused an error code greater than 1,
which triggers the stop of the boot process.

I don't understand why initscripts tries to fsck a non-existent device.

Definite problem here, too, on my uptodate Sid system, with ext3. My
fstab has lines like this:

LABEL=software /media/software ext3
defaults,user,exec,noauto 0 0

[The target is a LV within a VG on top of a partition on an external
USB disk.]

When the last field is 2, the boot stops after fsck fails with error
code 8, until I hit <ctrl>-D. From /var/log/fsck/fsck/checkfs

fsck.ext3: Unable to resolve 'LABEL=software'
fsck died with exit status 8

Maybe I should file a bug against initscripts.

Probably a good idea. I just changed the fs_passno field to 0, but a
bug is probably in order.

I had initially filed a bug against dosfstools but had no response:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=562536

Well, it's not really a bug in fsck, but, as you noted earlier, in
initscripts. Perhaps you can just reassign the bug?

I would just like to have USB flash drives that may or may not be
plugged into machines that aren't switched on all the time, and I would
like them to be mounted if they're plugged in when the machine is
powered on, and for the machine to boot anyway if the USB flash drive is
not present.

Exactly. But mounting automatically is not the problem. You can have
them mounted, without the fsck being performed.
