I just recently started working with a Sparcstation 1+ running SunOS 4.1. I must say that the experience has been a pleasurable one. But I've accumulated a list of questions that I was curious about - if anyone can help me, I would appreciate it. 1) How can I find out what the different fields in EEPROM mean and are used for. I've read the man page for eeprom, but the descriptions are not very illuminating. 2) Why would umount say a filesystem is busy when every indication says it is not? I was trying to unmount a filesystem used exclusively for user logins and umount kept saying the filesystem was busy. I was logged in as root at the console and no one else was logged in. I ran fuser to see what/who was using it, but came up empty handed. No programs are in the filesystem so they couldn't be running. I finally had to shut down the system in order to unmount the filesystem. What could be causing this and how can I get around it the next time it occurs? 3) Is the installation tape mountable? I would like to take a look at the contents of the installation tape, but have been unable to do so as of yet. How can I look at the contents and what is the format of the installation tapes? 4) I would like to execute programs for everyone that logs into the system. I'm running AT+T SysV at home and I know that /etc/login and /etc/cshrc are run before $HOME/.login and $HOME/.cshrc. Are their similiar files on SunOS? What program looks for .hushlogin and prevents motd from being displayed (or what causes motd to be displayed for that matter)? 5) Last one. I like to make what I call "emergency boot floppies" for all systems that I work on. I really can't do that with the Sun because the kernal itself in 1.4MB (I don't want to use munix, but rather the actual kernal being used on the system). Can I make a bootable tape that I can mount the hard drive onto? If so, how can I do this? I found the commands to format floppies and hard drives, but not tapes. Any suggestions? Thanx again for any help and thanx for reading this whole thing! Whew! Long one. P.S. Is there a FAQ for this newsgroup? If there is, could someone send it to me please? Thanx again.
