Otherwise this space will remain unavailable. For example, if someone chroot into wic image for applying some changes s/he wants to test before integrating into a recipe. An alternative to add extra space into the disk, is to add it directly into the rootfs with these two last options: part / --source rootfs [...] --extra-space 1G --overhead-factor 1.2 I developed wicshell.sh in order to automatize the operations of chroot into the .wic image and also sharing a folder with the host which is always useful when ssh/scp is not available. https://github.com/robang74/isar-nvidia-debian/blob/main/wicshell.sh Moreover, I saw that there are .conf files for producing vmdk and ova files. IMHO, a more general and flexible approach is to create these files directly from the .wic image, like in my project wicinst vmdk:$filename.vmdk [disk_size_in_gigabytes] wicinst ovaf:$filename.ova [disk_size_in_gigabytes] https://github.com/robang74/isar-nvidia-debian/blob/main/wicinst.sh I hope you are going to take in consideration this approach to simplify the access of these functionalities which are documented into my project README.md Every suggestion and critic in order to improve this approach will be welcome.

I have not in mind anyone but I cannot exclude that they exist. So, the two approaches can exist together as complementary ones. Or possibly, their .conf allows a more tunable output than a mere conversion which is easier to adopt during the development, instead. IMHO. > Best regards, R-

Here we take the most common and generic images and add some empty space at the end of then. This will enable better interactive use of our example images since people will have some space to install some more packages. While the space seems fixed it really is open end if the mass storage happens to be bigger, because we install expand-on-first-boot as well.
