Since commit6c40624930("bootconfig: Increase max nodes of bootconfig from 1024 to 8192 for DCC support") increased the max number of bootconfig node to 8192, the bootconfig testcase of the max number of nodes fails. To fix this issue, we can not simply increase the number in the test script because the test bootconfig file becomes too big (>32KB). To fix that, we can use a combination of three alphabets (26^3 = 17576). But with that, we can not express the 8193 (just one exceed from the limitation) because it also exceeds the max size of bootconfig. So, the first 26 nodes will just use one alphabet. With this fix, test-bootconfig.sh passes all tests.
