[pkg-cryptsetup-devel] Bug#901830: cryptsetup-initramfs: warning after upgrade cryptsetup-initramfs (update-initramfs -u / boot process)

[Antonio]

Thank for your reply.

The boot problem is that you include file "/lib/cryptsetup/functions"
[scripts: hooks/cryptgnupg, hooks/cryptopensc, hooks/cryptroot under
/usr/share/initramfs-tools] but when generate initramfs is updated and the
system rebooted, the file "lib/cryptsetup/functions" not exists in this
context.

For fix this, I created a simple hook (view below) and I updated initramfs
(update-initramfs -u).

Now, when boot, no error occour.


File /usr/share/initramfs-tools/hooks/fix-cryptsetup:

#!/bin/sh
set -eu
PREREQ=
prereqs()
{
  echo "$PREREQ"
}
case "${1:-}" in
  prereqs)
    prereqs
    exit 0
    ;;
esac
[ -r /usr/share/initramfs-tools/hook-functions ] || exit 0
. /usr/share/initramfs-tools/hook-functions

echo "fix missing file cryptsetup..."
mkdir -p $DESTDIR/lib/cryptsetup/
cp /lib/cryptsetup/functions  $DESTDIR/lib/cryptsetup/
exit 0
