[mythtv-users] Rethinking Xbox-Myth

I've got my mythbackend setup - now I'm going to setup an xbox as the
front end - it meets the "WAF" (Wife Approval Factor), and KAF ...
(Dad, this means we can get an XBOX - cool!)
I've already installed Eds-Debian - now it looks like I need to undo
that part. It was not clear to me that xbox-myth was in effect a
complete/alternate/replacement distro too.
I got reading the xbox-myth docs (what little their are) and got
thinking about it... All things concidered, i think there is a simpler
way of running xbox-myth as a frontend.
I know many of the pieces of this puzzle already and I'm quite willing
and able to work towards this and make this really happen.
Comments and suggestions any one?
Here's the idea:
A) I am behind a firewall I trust 100%, I think most people are too.
If not - why not? Why can't you drop most if not all security
protections? Just leave simple/crude ones in place. What must you
protect your self from? Your wife? Your kids? What?
I certianly don't have WMD I'm hidding in my home.
Ok dorm rooms/frat houses are a different beast.
B) Xbox-myth-frontend could (and should) use DHCP from the backend
server to configure its network settings. Remember - DHCP includes
lots of other features - like the "option root-path", so that the
client knows how to find its ROOT disk.
Busybox inside of the initrd has, by the looks of it, a DHCP client
built in right now, it can get all the information needed from
the dhcpd server on the backend.
C) The backend disk is HUGE, the xbox disk is TINY.
Why can't the xbox NFS mount ROOT from the backend? How much disk
io does an xbox myth frontend really generate? Remember - the Xbox
is wired, and supports 100mBit - as does nearly ALL things today.
Of course - /tmp and SWAP space would remain local to the xbox
besides - you now have more disk space on your xbox hard disk.
D) To configure, test, or update a front end is very simple,
three easy steps:
1) Backup xbox config before you mess with it.
bash$ su - root
bash# tar cfz /path/to/backup.tar.gz /nfsexport/xbox-root
2) Hack away
bash# cd /nfsexport/xbox-root
... hack hack ...
... done ...
3) Power cycle the xbox.
E) Ever screw up really bad? Solution 3 easy steps.
1) Cover your tracks:
bash# rm -rf /nfsexport/xbox-root
2) Restore from backup.
bash# tar xfz /path/to/backup.tar.gz /nfsexport
3) Power cycle the xbox.
F) What about 2 xbox front ends? Simple - make two
G) Customizing the xbox front end now is simpler - all of the xbox
myth files are now completely in the open - not burried inside of
several huge files on the xbox, and you don't have to update them
via ftp or burn a new cd?
