</div>My config sounds almost identical - btrfs-based master backend with<br>
front-end on nfs root.<br>
<br>
For updates to the front-end I usually just do them via chroot from<br>
the server - way faster than doing builds on an Atom.<br></blockquote><div> </div><div>Do you cross compile for the Atom? I haven't had much luck doing the chroot compiles, even for systems with the same architecture. Perhaps I need to do a better job of keeping the packages in sync across the FEs.<br>

I might see if I can write things up in a blog entry (if so it will go<br>
on planet gentoo). The biggest pain wasn't getting PXE+NFS working<br>
(no harder than setting up minimyth really), but fully building the<br>
front-end from scratch (lirc, X11 config for HDMI out, etc). I recall<br>
also having artifact problems with decoding video and such - I think<br>
mythtv 0.26 fixed that for me (newer version of bundled ffmpeg -<br>
videos would play fine with Gentoo's ffmpeg or mplayer, but not with<br>
the mythtv-bundled mythffmpeg).<br>
<br>
Oh, one thing I did do is just test the PXE+NFS from a diskless VM<br>
before moving to the actual front-end, so that I could take my time<br>
without messing up the TV. That doesn't help with some of the X11 and<br>
lirc work, but you can get pretty far on a VM.<br>
<br>
If anything working with NFS is much simpler - the kernel is the only<br>
thing that really needs special handling (and that is just a matter of<br>
replacing a file on the tftp server) - otherwise it is just like<br>
updating a chroot.<br></blockquote><div><br>Completely agree. <br> <br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
