Do you mean > mail? /rescue is a directory. Yes, I mean directory. I switch between unix and the other OS family and sometimes get sloppy with my terminology.

I measured this using kdf. The partition size is 512Mb. I was unable to write to the partition, and df was reporting 120% disk usage. Since I rm'ed the / rescue directory, kdf reports 23% disk usage and I can write to the partition. I thought that all the space was being used by /rescue, because kdirstat reported the size of the directory at ~400Mb, but after some experimentation, it appears kdirstat counts multi-linked files once for each link, so the directory may not have been taking up all that space. Regardless of the accuracy of kdf and kdirstat, I did receive a "disk full" message from "pw" on a partition which now has 380Mb free, so something funny is going on... > 100 MB should be plenty of space for the root file system assuming > that you have separate /usr and /var file systems (not something that > I recommend, but that's what the handbook recommends).

I have almost certainly made a mistake somewhere, but my goal is to find out what and not to repeat it. Things seem to be ok now (apart from I have no rescue dir). As far as I can tell, I understand links, but one can rarely know what one doesn't know ;-) Regards, Rich
