Did you actually bother to read his report? While his example is used "/", if the report is correct then you just need to replace "/" with the path of any file system mount point that is world writable like say "/tmp". Do you have /tmp mounted like this? /dev/ad0s4e 507630 162050 304970 35% /tmp Have you tried using "/tmp" or some other suitable mount point before slinging off with the old Doctor joke? Even if it is only "/", having the system die and not be recoverable due to having a excessive number of files in "/" is a critical error. I'm sure you have *never* accidently copied a set of files to "/" in your life. Me, I know I've made that sort of mistake in the past, and as I'm not perfect, I'm sure I'll make that sort of mistake at some point in the future. I would however like the machine not to fallover when I do make that mistake. Now why don't you be constructive and verify whether the report is valid or not. I don't have a spare machine to test it on so I'm not going to attempt it.
