If so, this will skew the "average system" away from binaries. b) What percentage of the disk is used for maintenance information for the file system? Average according to a Bell Labs Techinical Journal I have seen is 17%. This does not include the 10% reserve, nor does it apply to anything other than UFS without immediate files/links. c) Is the block/fragment size large so that there is a lot of hidden cost in files? You'd probably be better off posting a program/shell script which you ask people to run overnight that "evaluates" their disk, and then let them post the results; the questions all have potentially subjective answers (ie: is a shell script a text file? Does it constitute "source" or "binary" code?). Regards, Terry Lambert terry@cs.weber.edu --- Any opinions in this posting are my own and not those of my present or previous employers.
