 for DCC support

Hi everyone,

It looks like this broke the bootconfig tests (tools/bootconfig/test-
bootconfig.sh), tested on 6.1.18:

Max node number check
test case 12 (./bootconfig -a ./temp-HCfT.bconf ./initrd-NGHv)...
Apply ./temp-HCfT.bconf to ./initrd-NGHv
        Number of nodes: 1024
        Size: 8110 bytes
        Checksum: 599485
\t\t[OK]
test case 13 (./bootconfig -a ./temp-HCfT.bconf ./initrd-NGHv)...
Apply ./temp-HCfT.bconf to ./initrd-NGHv
        Number of nodes: 1025
        Size: 8118 bytes
        Checksum: 600212
\t\t[NG]

When I adjust the max node number for the tests to 8192, test case 13 passes, 
but test case 12 then fails:

Max node number check
test case 12 (./bootconfig -a ./temp-qZHF.bconf ./initrd-0v99)...
Error: Config data is too big.
\t\t[NG]
test case 13 (./bootconfig -a ./temp-qZHF.bconf ./initrd-0v99)...
Error: Config data is too big.
\t\t[OK]

Grs,
Heinz
