Didn't see the later report - wrongfully assumed someone else reporting
would have unarchived this one.
However, I suggest whether or not the network adapter requirement is
documented (even if it wasn't documented it's a no-brainer), the
resulting behaviour of the script in the absence of a network adapter
added to /etc/initramfs-tools/modules is a bug and should be gracefully
detected.
Imagine the scenario someone installs dropbear-initramfs and does not
yet get around to reading the full documentation. A reboot of the
system at that point can very easily cause loss of control of the
system. A package install alone should never render a system
unbootable, which this one can.
