Give us the steps you went through when building your ramdisk image before
compressing it.
Should be something like:
$ dd if=/dev/zero of=ramdisk.img.nogz bs=1k count=$RAMSIZE
$ /sbin/mke2fs -q -F -m0 ramdisk.img.nogz
$ mount -o loop ramdisk.img.nogz ramdisk
% This is the point where I copy the contents into the image %
$ umount ramdisk
$RAMSIZE is the definition for the size of the ramdisk image. If it is not
large enough strange things can happen, espcially if the needed size is
close to the built size.
John
P.S. du -sh will give you a directory's size. Man it to get options.
There is a recursive option.
