Title:
  encrypted root fails to cryptsetup on disco

Status in cryptsetup:
  New
Status in initramfs-tools package in Ubuntu:
  Confirmed

Bug description:
  There is a subtle error message during update-initramfs:

      find: '': No such file or directory

  I could trace this to /usr/share/initramfs-tools/hooks/cryptroot line
  430:

      # libargon2 uses pthread_cancel
      LIBC_DIR="$(ldd /sbin/cryptsetup | sed -nr 's#.* => (/lib.*)/libc\.so\.[0-9.-]+ \(0x[[:xdigit:]]+\)$#\1#p')"
  >   find -L "$LIBC_DIR" -maxdepth 1 -name 'libgcc_s.*' -type f | while read so; do
          copy_exec "$so"
      done

  ldd output shows:

          libc.so.6 => /usr/lib/x86_64-linux-gnu/libc.so.6
  (0x00007f41aa8c4000)

  so the library is not in /lib anymore but /usr/lib

  The root cause of this may be an update to libc, however the script
  may need adjusting anyway.
