[Pkg-vsquare-devel] Bug#671695: fuseiso9660: copies from fuseiso9660 mount aren't reliable

[nick black]

Package: fuseiso9660
Version: 0.2b-1.1
Severity: grave
Tags: upstream
Justification: causes non-serious data loss

Dear Maintainer,

I am using fuseiso9660 for the creation of my modified debian-installer ISO.
simple-cdd creates a standard debian unstable netboot installer ISO, which
I then mount as a FUSE-capable user. I copy files from the FUSE mount into
a new directory, from which I make a new CD (using grub-mkrescue).

I was getting regular MD5 errors upon unpacking udebs from the CD (installer
step, "Load installer components from CD"). I checked, and the MD5s were
indeed incorrect on many of the new ISO's packages.

I verified that this was occurring before running grub-mkrescue and after
running
simple-cdd -- that is, when copying from the fuseiso9660 mount. I then added
the following options to fuseiso9660:

 -s -o noauto_cache,read_sync

all problems went away immediately and reliably. I'm not yet sure which of
these
options are necessary, but all three together definitely work.

This can introduce data loss if the user assumes the copies have been performed
with fidelity, and removes the original media.
