I have a powerpc mac, I know about yaboot.

You have read the new section on the homepage about how Emdebian can
only indirectly support low resource machines like powerpc macs?
Emdebian Grip, in particular, is *binary compatible* with Debian and
therefore every package has precisely the same memory footprint and CPU
requirements as the same package in standard Debian. Using Emdebian Grip
does *not* give you any performance advantages within the packages
themselves - it is roughly equivalent to installing exactly the same
packages from standard Debian on your machine and putting /usr/share on
an external USB stick.

I have a powerpc (iBook G4) that still runs Lenny - I would not dream
of using Emdebian on it, there will be no advantages. True, that one
still runs a full GNOME environment but if I changed that to XFCE,
there would be no gains over an Emdebian Grip installation of XFCE.

Powerpc macs like the iBook had reasonable hard drives and support
expansion fairly easily - they are not usually described as embedded.

grub already exists:

(When searching, ensure you select the appropriate architecture if a
package only exists on certain architectures - the default is ARM which
doesn't use bootloaders at all.)

See: http://lists.debian.org/debian-embedded/2008/12/msg00023.html


If you want more packages added, set up a Debian machine or chroot with
all the packages you need (and only the ones you need) and send the
complete output of 'dpkg --get-selections' to this list.

Alternatively, file RFP bugs against buildd.emdebian.org at wishlist

To see the current list of packages, use the search support:


Emdebian Grip is a filtered repository - packages have to be added
explicitly, then their dependencies. This has a huge bonus at runtime
because the dpkg and apt database is far, far smaller than any Debian
system (about 100 times smaller currently).

I've added yaboot though.

em_autogrip: INF: adding source package to locale using reprepro
Exporting indices...
em_autogrip: INF: adding powerpc packages to grip using reprepro
Exporting indices...

Later on, I'll get the emdebian-grip package uploaded to the Emdebian
Grip repository so that you can download and grip any package you like.
Indeed, I'm thinking of splitting emdebian-grip out of the
emdebian-tools source package to make this easier.

To do that, I need to make some more improvements in the emdebian-grip
package, hence the testing.

One step at a time.
