Public bug reported:
Binary package hint: cryptsetup
This bug is *not* a duplicate of bug #85460
cryptsetup fails for encrypted rootfs on a device that is slow to come
up (i.e. an external USB HD). The "udevsettle" solution proposed in bug
#85460 does not help.
I have patched /usr/share/initramfs-tools/scripts/local-top/cryptroot by
integrating into it the same kind of "waiting loop" that already exists
for a non-encrypted rootfs, in /usr/share/initramfs-tools/scripts/local
.
This patch to /usr/share/initramfs-tools/scripts/local-top/cryptroot
solves the issue and perfectly does the trick. Please consider
integrating this fix.
