From fb951b93423356a7b648a8e268cd5af57d964f45 Mon Sep 17 00:00:00 2001 From: Peter Korsgaard Date: Mon, 19 Apr 2010 14:24:11 +0200 Subject: fs/ext2: fix blocks/inodes calculation With the ROOTFS_TARGET conversion, EXT2_OPTS gets evaluated very early (before TARGET_DIR is populated with files), so the calculated blocks/inodes numbers are wrong. Fix it by moving the calculation to a shell script wrapper around genext2fs, so it only gets executed just before genext2fs runs.
