<br>
I have a system here that creates a dozen images for medias of different<br>
sizes, installing a few dozen machines every day. I would like to make<br>
the process more unified - install the same 4G image on all medias (dd)<br>
and then maximize sda6, the last ext3 partition, and naturally, the<br>
underlying extended partition sda4.<br>
<br>
The only tool that automates resizing like that is parted, and it still<br>
needs a precise partition length instead of "use all available space",<br>
and won't resize ext3 if I don't turn off the journaling first (make it<br>
ext2). I tried deducing the maximum partition size with fdisk -l and<br>
other sfdisk instead, but each uses different units and I have no idea<br>
how to convert them all correctly so I'm left with working, non<br>
overlapping partitions.<br>
<br>
I'm prepared to do it the hard way, I just wondered if there's a tool I<br>
missed or an existing script that already does this.<br>
<br>
Thanks.<br>
