I apologize for not reading through the messages you referenced in the
initial bug. I think you had several good ideas; in particular using
the ramdisk for the lockfile and providing a --no-lock option for dpkg
seem like good options. Perhaps there's even a semaphore capability
in the kernel that wasn't available when dpkg was written.
Anyway, boot-floppies is now officially dead. This is definitely a
bad bug for people installing to nfs; I guess the thing to do is
document a workaround.
What would you recommend? Have nfs-common available on your boot share
so it can be manually installed into the ramdisk system sometime
before base installation?
