[mythtv-users] diskless Mythtv USB

Thanks for getting back to me.
I come from an IT background well rooted in Linux services ie Apache, MySql
DNS. But when it comes to distro, I have always been most comfortable with
Redhat / Fedora.  I am willing to try mini myth for the front end EPIA
motherboard, but for the backend I would still like to keep Fedora.

Can the current release of minimyth (Minimyth-0.5.1) be used with the most
recent MythTv backend?

I am still wondering if it will be easier to net boot or boot from USB?

If you are familiar enough with Linux, I suggest you not use Fedora
for this.  http://linpvr.org has mini-myth ( a distro designed for the
Epia boards ) or use something like Gentoo or a Debian flavor.  Mainly
because these options provide more flexibility from the end user on
tailoring it to your needs (A usb device).  It can certainly be done
with Fedora, but I think less modding would be necessary if you used a
distro designed to work better with your customizing.

If you choose to go NFS, it's a fast boot process.  I don't know how
fast you are looking for, but a network booting machine on my network
is maybe 2-5 seconds slower than my hard drive booting machines (of
the similar layout/daemon starting, etc).

2.  IR:  I would grab a serial receiver from http://irblaster.info and
just configure my system to use it as my receiver.  It's a cheap (and
easy) solution, and the SP13000 do have serial connectors, so if it's
not being used, it's a good option.
