Installed the new XOpup on a "bone" usb drive

Installed the new XOpup running on the OLPC XO 1.0.

This doggy bone USB key was on sale for 75% off:

 and here it is installed :
there were only pink ones left;  I suppose a white one would match better...

More Upgrades: F16 from F14

Ok, not such a good idea;

Hit a known bug: preupgrade from F14 is not good...

So had to re-install the OS ...

Minor complications:
This machine does not have any CD/DVD drive;
so working from USB keys.


Current Issues with my system:

0) SELinux seems problematic,  have disabled, need to work on this.

1) httpd did not restart, needed to manually configure
--> the new UI for system config service is missing this one...

2) mysqld did not restart: see  (1)

3) mythbackend did not restart:  May need to redo installation;
working on this.

notes:
all issues are working if I manually started the services as root, so the binaries updated fine with F16, it is just the startup/permissions/users that needs work.

shh, an AMD Fusion E-350 'upgrade' at home

or:
Retiring the Shuttle ... PC

A new quiet and low power system has replaced older hardware.  The new system is working great, not much faster but much quieter.

Details:


After a system failure, needed to repair an existing Linux system.

I could have tried to repair the motherboard, but I have done that twice before. 

Instead decided to retire the old board, and replace it with a modern passively cooled AMD E-350 one.

A direct motherboard, memory replacement  and power supply.  The power supply was still ok, but was an older one with a 20 pin connector, not a newer 24 pin.
The memory was also ok, but the new system uses DDR3 ram; older was only DDR2.


Fedora 14 update notes:

1) X on the new system is not quite perfect.
Since it is a very new system, only Fedora 15 or 16 has the latest drivers/kernel

Fedora 14 works well enough for now;
Planning to update to 16 when it goes gold anyway.
(next week?)

2) Network changed.  Using DHCP, and auto configuration of the network, I now have a new IP address.  No real surprise, but some of MythTV did not expect this. Needed to reconfigure.

3) older celeron was a 32 but kernel,  new system has more ram (8G), so added the  PAE kernel.

very simple

 yum install kernel-PAE.i686

4) sensors also are not working;
again will need to update Fedora with a new kernel before spending too much time on this.
