When managing UML images, I typically create a new image of the same
size and then rsync across them. This is not the most efficient, but it
is the most reliable. I''ve tried changing the seek parameter of an
image
using dd for an image, but I''ve found that resizing filesystem often
fails or does not take effect.
You could try changing the seek of the image and then running resize2fs
against it, but I''d bet you $1 you''d lose that data. Safer to
try
something like this:
dd if=/dev/zero of=additional.img ...
cat fedora.img additional.img > new.img
resize2fs new.img
I''m sure there''s other ways. I''ve seen this discussed
on the
user-mode-linux.org site.
