Hi,
After building your image, you should see the sizes listed for example
( otherwise, I am not sure you want to use df on your host ):
WARN: /auto/freescale/ltib/ltib-mpc8544ds-20071122/rootfs.tmp/sbin/
ldconfig statically linked
Filesystem stats, including padding:
Total size = 343396k
Total number of files = 13263
Your ramdisk exceeds the old default size of 4096k, you may need to
set the command line argument for ramdisk_size in your bootloader
allowing 10% free this gives 377735k . For instance, for u-boot:
setenv bootargs root=/dev/ram rw ramdisk_size=377735
creating an ext2 compressed filesystem image: rootfs.ext2.gz
creating a uboot ramdisk image: rootfs.ext2.gz.uboot
Image Name: uboot ext2 ramdisk rootfs
Created: Fri Mar 14 11:57:51 2008
Image Type: PowerPC Linux RAMDisk Image (gzip compressed)
Data Size: 111426142 Bytes = 108814.59 kB = 106.26 MB

Build Succeeded
cheers,

If I want to calculate the uncompressed size of an image can I just
add
the packages I want. Build it. Change directories to "rootfs" and
run
"du . -ckS"? Here is an example...
address@hidden rootfs]$ du . -ckS | sort -rn | head -n 20
