I can confirm that on Solaris 2.5, bin is the owner and group of most files in /bin, /usr/bin, et al. I don't go back all that far in unix, so I don't know why that is. > sys: > > HELP: As with bin, except I don't even know what it was good for > historically. > > I'm told that /dev/vcs* and /var/spool/cups are owned by > group sys, dunno why. On the same Solaris box, the sys group seems to be used similarly to adm, but for some system programs rather than logs. The Sun package management stuff all seems to be group sys, for example. My OS X box has both groups, but I can't find where either of them are used. One thing that might be interesting to know is where the original passwd and group files came from. If they were originally copied from some other unix system early in Linux's history, that might explain why we've got sys and bin: wherever they came from had sys and bin. Or maybe not. :) - Aaron -- So: My point is that [Microsoft] may have a ton of money and be more vicious than a junkyard dog, and have a stranglehold on dimwitted IS managers, but they're just not very _competent_. -- Rick Moen, on macosx-for-users
