With this configuration: [buildnr_from_file] suffix=uy path=uy-buildnr-0.88-1.5 When the version number has three digits the process fail. Seems like the image name couldn't have more than nine characters. For example with the image name: os100uy.zd the process fail. Its very strange, because I know that many dextrose builds have long names. <pre> </pre> If i change <div class="gmail_quote">On Wed, Oct 6, 2010 at 11:24 AM, Bernie Innocenti <<a href="mailto:bernie@codewiz.org" target="_blank">bernie@codewiz.org</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div>On Wed, 2010-10-06 at 09:42 -0200, Daniel Castelo wrote: > Hi!

Here's the relevant code: 48 local img_sectors=$(sfdisk -uS -l $img | grep img2 | awk '{print $4}') 49 echo "(1 losetup error is normal here)" 50 losetup -d /dev/loop6 || : 51 losetup -o $((8192 * $BLOCK_SIZE)) --sizelimit $((131072 * $BLOCK_SIZE)) /dev/loop6 $img 52 echo "(1 losetup error is normal here)" 53 losetup -d /dev/loop7 || : 54 losetup -o $(((8192 + 131072) * $BLOCK_SIZE)) --sizelimit $(($img_sectors * $BLOCK_SIZE)) /dev/loop7 $img The error probably occurs because $img_sectors is uninitialized. Try adding some debug stamennts just after line 48. For example: echo '*** BEGIN DEBUG ***' sfdisk -uS -l $img echo '---' sfdisk -uS -l $img | grep img2 echo '---' sfdisk -uS -l $img | grep img2 | awk '{print $4}' echo '*** END DEBUG ***' -- // Bernie Innocenti - <a href="http://codewiz.org/" target="_blank">http://codewiz.org/</a> \X/ Sugar Labs - <a href="http://sugarlabs.org/" target="_blank">http://sugarlabs.org/</a> </blockquote></div> -- Ing.
