The manual suggests backing up /etc "as a precaution" and says that "you will not normally need to restore any of the files on this diskette" ! WHAT ? !!!! Other Sun upgrade instructions have done a much better job here, telling you what files need to be saved and restored. I had to rebuild all this account stuff. I did it by hand (didn't use SNAP). If you're familiar with Sun system administration you should be able to do this by saving and restoring the files in /etc but I haven't tried this. Be sure and familiarize yourself with the material in "Sun386i Advanced Administration" - which tells you how to do manually the stuff SNAP tries to do for you. - Glenn Roberts, The MITRE Corp., McLean VA (703) 883-6820 gfr@cobra.mitre.org

This precludes the use of SNAP for system administration which is considered a blessing around here. SNAP seemed to be very slow and combersome, especially when minor changes were needed to be made. I agree with Glenn, it is best to do system administration by hand. All the information to do so is either in "Sun386i Advanced Administration" or in "System & Network Administration" manuals. When upgrade time did come, we had learned enough by then to know which files needed to be saved on disk (also printed) so that after the 4.0.1 was loaded, the admin. files could very quickly be restored from disk. The greatest amount of time was spent actually loading the tapes on the disk, not going through the hassle of re-entering all the admin. information through SNAP. Even if SNAP was made to run under the X windows system, we wouldn't use it. Mike Michael P.
