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

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

- BR2_TARGET_ROOTFS_EXT2_RESBLKS is ignored if it is 0. It should be used if it is 0 (since 0 means something here--"do not reserve any blocks". Thanks to timw. Closes #484. 2006-12-22 13:34:35 +01:00			`ifneq ($(strip $(BR2_TARGET_ROOTFS_EXT2_RESBLKS)),)`

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.
