However, in the z/OS Unix System Services planning manual, in the section titled "Establishing an /etc file system for a new release", it specifically states the following: "Because IBM products do not create files into /etc, there is no possibility that SMP/E installation of an IBM product or service will overlay your own files within /etc." (thanks to Shmuel for the pointer to that manual - I was looking in the MVS Planning manual and Severpac manuals) It doesn't specifically mention this about /var, but I assume it is also true. So going back to the OP, I don't know when his symlinks were removed and I have never run into that problem, and there should be no harm in keeping them as symlinks in his maintenance / service root file that get's cloned. -- Mark Zelden - Zelden Consulting Services - z/OS, OS/390 and MVS mailto:m...@mzelden.com Mark's MVS Utilities: http://www.mzelden.com/mvsutil.html Systems Programming expert at http://expertanswercenter.techtarget.com/ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
