From 637ad7ef8c3e0bbfcff1df6b0039446d2b251cf8 Mon Sep 17 00:00:00 2001 From: Kevin Tian Date: Tue, 27 Jul 2010 14:45:10 +0800 Subject: bitbake.conf: change inode calculation for genext2fs [BUGFIX#138] genext2fs 1.4.1 creates minimal inode number based on specified rootfs directory. This is desired in some embedded devices as storage/memory are precious. However it's not suitable in development phase where target rootfs may be changed heavily on the fly (remote debug, test, ...). Sometimes this may even cause "No space on device" error due to limited free inodes exhaulted at the 1st boot. Here a new option is added to allow falling back to original 1.3 behavior, i.e caculating inode number based on specified bytes-per-inode parameter.
