We need to calculate filesystem size right when we run genext2fs. As was, size was calculated right when 'make' was run, at which point the rootfs may well be empty... 2005-02-12 05:32:17 +01:00			`EXT2_OPTS :=`
A patch from Arne Jonsson to calculate fs size, with adjustments by me. 2002-10-23 09:56:20 +02:00
target/: get rid of unneeded $(strip ..) 2008-12-08 09:15:58 +01:00			`ifeq ($(BR2_TARGET_ROOTFS_EXT2_SQUASH),y)`
Do not squash perms, just owner 2005-02-19 00:58:16 +01:00			`EXT2_OPTS += -U`

Patch from gtj -- http://bugs.uclibc.org/view.php?id=39 0000039: Adds options to ext2 filesystem creation Adds ability to specify block and inode counts, reserved blocks, permissions squash and device table in the configuration. Also adds capability to gzip output and to copy the resulting image to a secondary location like a tftp server's root directory. 2005-01-23 11:53:06 +01:00

fs/ext2: fix typo BR2_TARGET_ROOTFS_EXT2_RESBLKS is an int, so test against 0 rather than the empty string - Otherwise the test is always true and a -m option without arguments is added to the argument list, causing genext2fs to get confused.

ext2: convert to ROOTFS_TARGET infrastructure We also remove the BR2_TARGET_ROOTFS_EXT2_OUTPUT option, that could be used to specify an alternate name for the generated image file.

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.
