Re: Doubts about Debian8.1 DVD ppc64el image

Hi,

inspection of the ISOs is not needed any more, since we now know
that your algorithm expects "powerpc" bootable ISOs, not those
for "ppc64el".
Nevertheless, as we are at it:

That's CHRP without HFS.

Dear packagers: Version 1.4.0 is out :)


The debian-7.8.0-powerpc-netinst.iso yields:

The difference between ISO size and partition size probably
comes from genisoimage default padding of 300 KiB.
I think this is not fully CHRP compliant.
Shrug.


Have a nice day :)
