@cyannella Ok here is an updated init that calculates the MD5 sum of the captured image file. https://drive.google.com/file/d/13eknbYjZhpnsbfi7B_JpVY7KRe_n2xTw/view?usp=sharing
Download that file as init_md5.xz and copy it to /var/www/html/fog/service/ipxe directory on the fog server. It has a unique name so it will not overwrite anything FOG.
Now take ONE host where you can recapture an image. Go into the host definition and for the host init field enter init_md5.xz and then save the settings. Configure a capture task and then recapture your image. For every d1pX.img file there should be a d1pX.md5 file that contains the md5 hash of the file.
Just a note, a 16GB partition took about 15 seconds to calculate the md5 hash.
Lets see how this runs in your environment.
