cp /home/pozzoe/temp/easyubuntu/conf/hdparm.conf /etc/hdparm.conf
Executing:
cp /home/pozzoe/temp/easyubuntu/conf/hdparm.conf /etc/hdparm.conf
error:
cp: no se puede efectuar `stat' sobre «/home/pozzoe/temp/easyubuntu/conf/hdparm.conf»: No existe el fichero o el directorio

(the last error messages are in spanish:
cp: can't stat /home/pozzoe/temp/easyubuntu/conf/hdparm.conf
No such file or directory)

In fact, the file doesn't exist.

I can confirm that as of rev 164 the hdparm.conf is missing from /trunk/ .

A function call to write the lines
/dev/cdrom {
    dma = on
}
into the correct file would be nice, which saves overwriting a file. I'll give it a try, but i dont think its going to happen.

taken with 'svn diff packagelist-breezy.xml > packagelist-breezy.xml.diff' against rev 164.

The python backend does not handle redirection, so this patch will not work. This should not be a problem in dapper, as most devices which should have dma enabled have dma enabled.

Looks like we would need add a function/change the backends to process these redirections appropriately.
