Waterloo, Ontario. Lines: 46 I received Microport's 2.3.1 on monday. The improvements over 2.3.0 seem minimal, but some will be nice. I'm glad to see they are providing the tape driver software as part of the package, too bad we just bought these drivers 3 weeks ago! The entire installation notes assume that you are upgrading from 2.2, not from 2.3.0. This is unfortunate as there are some things that must be considered if 2.3.0 is the current system. My greatest fear and the reason I've procrastinated installing 2.3.1 so far is that the install is going to overwrite all kinds of system files that I have modified for our site. It's not the obvious ones that bother me, /etc/passwd, /etc/groups, /.profile, etc. I will save these. It's the ones that I've forgotten about that bother me. Ones that other packages we've installed have modified without my realising it. For example, if Rabbit's 3270Plus software installation had worked, it would have modifed /usr/linkkit/lib2. But since lib2 is so big, microport's ar command was not able to add Rabbit's drivers to it. Therefore I had to muck around with this installation by hand and I (think I) know what files are to be saved. Never mind that Rabbit should never have tried to modify system files. They did. What other files may have been changed? Oh yea, I'll bet all the crontabs are different, and how about /etc/profile, inittab, gettydefs, TIMEZONE, bsetdate, fstab, issue, motd. And in /usr/lib/uucp, my goodness, I'd hate to lose anything there. And it's been months now, but I remember adding some aliases to /usr/lib/mailx/mailx.rc. And what is going to happen to my lp setup. Will the install modify any files in /usr/spool/lp? I've just scared myself so badly writing this that I may not be able to bring myself to install the upgrade. larry -- Larry Williamson Focus Automation Systems UUCP: watmath!focsys!larry 608 Weber St. N, Waterloo, Ontario N2V 1K4 +1 519 746 4918
