Please unblock package amd64-microcode
Unfortunately, both amd64-microcode and intel-microcode can trigger a very
nasty bug in initramfs-tools that renders the initramfs unusable, and
therefore may make the system unbootable.
It will only happen when initramfs-tools is incapable of creating ORDER
files (e.g. because of noexec $TMPDIR or noexec /tmp with $TMPDIR unset),
so it should be pretty rare. But still, the consequences are dire...
kinda like some of the processor errata the packages fix, I suppose :-)
This has bitten an user of intel-microcode. Please refer to bug #689301
and #688794.
This upload works around the bug in initramfs-tools, which is the safest
way to go about it (especially considering backports).
