> if the files/logs that are taking up space are written by the root user then it's a moot point Yeah. Sorry if my comment was a bit unclear but what I meant to say is that because of this reserved amount I could see it being the case that one machine is still able to finish booting even though the hard drive is “full”, because it is using the reserve capacity to allow processes to write to disk. Whereas the other person that was unable to boot may have either been using a different file system without reserved amounts, or have settings that made it so reserve was set to 0, or their machine could have been actually physically out of space.
