[ipxe-devel] Does imgextract keep writing to same named location by design?

Hi Michael,

You are triggering slightly undefined behaviour by using both

Success!! This was where my confusion was shooting me in the foot, thanks
for the explanation. Once I stopped naming the images and only passed
initrd.magic on the boot line things are working and a few dozen reboots
into testing seem to be reliably predictable with the last archive winning
in the case of multiple files.

Thanks!
