I've prepared a partman-prep package which should add support for
PReP boot partitions to the installer. The package has been forked
partman-palo. Now, short before testing, I'm wondering about the
mechanism which takes care about loading this module.
I've grep'ed through the complete installer source, but got stuck in
the partman code. So - what do I have to do, that the partman-prep
gets loaded on installation time?
Same as partman-newworld: Priority: standard is enough to have it
installed automatically. Make sure to use proper Architecture: and
XB-Subarchitecture: fields to make sure it's not installed where it's
inappropriate, and if necessary an isinstallable file in the control
Ah - thanks for your answer. I didn't set the XB-Subarchitecture
because it wasn't set in the control file. In case of the newworld
I can't find where powermac_newworld comes from. What to do if I only
want to have this loaded when using the pseries flavor added by me in
the linux-kernel-di-powerpc's kernel-versions file?
It is from archdetect which comes from the ddetect .udeb. We need to
support for your hardware there. Can you give us the /proc/cpuinfo of
machines, so we can identify it properly ?
Sure will do or will send patches for archdetect.
In any case partman-prep should be installed on all of the IBM
machines : all
prep (even ppcbug i think), IBM chrps and the newer pseries and what
While looking for the way to set the correct subarch, I found that in
base-installer's postinst, line 438 the CPU variable is filled by:
CPU=`grep '^cpu[[:space:]]*:' /proc/cpuinfo | cut -d: -f2 | sed 's/^
*//; s/[, ].*//' | tr A-Z a-z`
The following case doesn't seem to work with more than one CPU. In
my case CPU contains "power4+ power4+".
Where did you find it ?
As written above in the base-installer source package, file
line 438 ;-) Its the point where the installer chooses the perfect
the installation. I had to add a "case" for power4+|power5+ and set the
flavor to pseries. Maybe this should be renamed to ibmppc, because it
applies to iSeries and the other IBM ppc machines, too.
