No! There are services that we shouldn't run on an audio production

It's hard to say what should be disabled and what doesn't matter.

For example, I don't think this counts on my machine regarding to
$ grep noatime /etc/fstab
/dev/sda11				  /mnt/music	  ext3	  noatime,defaults    0       2
/dev/sdb12				  /home/music	  ext4	  noatime,defaults    0       2
but on another machine noatime might have impact to the performance.
