From 0f0d0a77ccbdc6bfe51c0d184f92d99ebcc2e809 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Wed, 5 Feb 2020 22:50:13 +0900 Subject: tools/bootconfig: Show the number of bootconfig nodes Show the number of bootconfig nodes when applying new bootconfig to initrd. Since there are limitations of bootconfig not only in its filesize, but also the number of nodes, the number should be shown when applying so that user can get the feeling of scale of current bootconfig.
