Hi,<div><br></div><div>You can also create an empty image with a template similar to this one (see [1] for more info):</div><div><br></div><div><div><font class="Apple-style-span" face="'courier new', monospace">NAME = new_img</font></div>
<div><font class="Apple-style-span" face="'courier new', monospace">TYPE = DATABLOCK</font></div><div><font class="Apple-style-span" face="'courier new', monospace">SIZE = 512000</font></div>
<div><font class="Apple-style-span" face="'courier new', monospace">FSTYPE = ext3</font></div></div><div><br></div><div>Or create an empty disk instead, as explained in [2].</div><div><br></div><div>You can change the boot device with the OS/BOOT attribute, see [3].</div>
<div>Regarding your last question, "<span class="Apple-style-span" style>Do I really have to delete and recreate it?</span>", you can change the template with the command 'onetemplate update', and the next instance will use the new boot attribute.</div>

</div></div>Hmm, I feared these kind of answers. :-(<br>
Such a workflow unacceptable for my end-users.<br>
