==== Local Packages ====

 * Updated `fetchyahoo` to 2.10.8

==== Fedora Upgrade ====

Made a start on upgrading my home machines to Fedora 7.
First up was my firewall/web/DNS/ftp/mail server machine, which I've set up
to be able to run two different OS releases, with the data shared between them.
I only had time to do the base Fedora 7 install, and the only point of interest
really was that I needed the `libata.ignore_hpa=1` hack (see FedoraProject:Bugs/F7Common)
to get the partition table on the smaller of my 80GB disks to be recognised.

I wanted a way to choose between the two OS releases at boot time.
With `grub` having been installed on the MBR, I only had the option of booting into the new Fedora 7 installation.
As a quick fix, I copied the Fedora Core 6 boot entries from the Fedora Core 6 version of `/etc/grub.conf` and
appended them to the Fedora 7 `/etc/grub.conf` file. That gave me a way to get into Fedora Core 6.
A more long-term fix was to have each OS release's version of `grub` able to load the other OS's version.

I added the following to the Fedora Core 6 `/etc/grub.conf`:
{{{
title Fedora 7 Boot Menu
        rootnoverify (hd0,1)
        chainloader +1}}}
and this to the Fedora 7 `/etc/grub.conf`
{{{
title Fedora Core 6 Boot Menu
        rootnoverify (hd0,0)
        chainloader +1}}}
I have disks on this system installed as pairs and everything mirrored (RAID1).
The Fedora Core 6 `/boot` is the first partition of my first hard disk pair, and the Fedora 7 `/boot` is the second partition.
All that was needed now was to install each OS release's version of `grub` into the `/boot` partition for that OS release and
then my two `grub` versions would be able to load each other.

I used the standard RAID1 `grub` installation route:

On Fedora Core 6:
{{{
# grub
grub>  device (hd0) /dev/hda
grub>  root (hd0,0)
grub>  setup (hd0,0)
grub>  device (hd0) /dev/hdb
grub>  root (hd0,0)
grub>  setup (hd0,0)
grub>  quit}}}
On Fedora 7:
{{{
# grub
grub>  device (hd0) /dev/sda
grub>  root (hd0,1)
grub>  setup (hd0,1)
grub>  device (hd0) /dev/sdb
grub>  root (hd0,1)
grub>  setup (hd0,1)
grub>  quit}}}
Note that in Fedora 7 all disks are regarded as being SCSI disks, so the device names change (check `/boot/grub/device.map` too).
