I started re-working the problem, looking at it from the perspective of dealing with the size *before* using dd - shrinking the filesystem using resize2fs, and then shrinking the partition to match, rather than trying to shrink the entire card image as a single unit. After that, then I can take an image of the shrunk SD card.</div><div id="bloop_customfont" style="margin:0px"><br></div><div id="bloop_customfont" style="margin:0px">Researching the approach, I came across a super easy been-there-done-that shell script which can take the image and shrink it appropriately for the Pi:</div><div id="bloop_customfont" style="margin:0px"><br></div><div id="bloop_customfont" style="margin:0px"><span class="Apple-tab-span" style="white-space:pre"> </span><a href="https://github.com/Drewsif/PiShrink/blob/master/pishrink.sh">https://github.com/Drewsif/PiShrink/blob/master/pishrink.sh</a><br></div><div id="bloop_sign_1542137001127542016" class="bloop_sign"><br></div><div id="bloop_sign_1542137001127542016" class="bloop_sign">Bonus, this also sets up the pi to automatically expand to fill the card, which I was also going to have to figure out how to do. He does some interesting things in the script, especially at the end using parted and truncate.</div></body></html>
