[Sugar-devel] XO Fedora 22 Beta work

[Samuel Greenfeld]

James and I looked a bit into the systemd issue last night & discovered the
same.  This was discussed at
http://lists.sugarlabs.org/archive/sugar-devel/2014-May/048180.html

A solution to solve this may be tricky.  Currently no one may be available
to look into getting newer Linux kernels working on XOs.  And if a newer
kernel was tweaked for XOs and brought in, extensive testing against
multiple XO models & variants (wireless cards/cameras/memory chips/etc.)
would be required.

Bringing in an older systemd with userspace firmware loading support might
be easier in the short term, but could break RPMs dependent on newer
systemd versions.

I don't know what resources OLPC has internally at the moment, but this may
be beyond what part-time volunteers can do, especially if support is
desired for XO models which OLPC no longer sells.
