I recently upgraded a Sun-4/280 running SunOS 4.0.3 to a SPARCserver 490 running SunOS 4.1. I have the following observations: The hostname is now in /etc/hostname.xxn (xxn is the name of the ethernet interface). If you use emacs you have to be careful not to leave /etc/hostname.xxn~ files around. They confuse /etc/rc.boot. In order to enter the host's IP address in suninstall you must re-select the ethernet interface even though it already has an 'x' next to it. top has to be recompiled. The -p option to ps is no longer allowed. It was redundant anyway. calendar is no longer run by default in crontab. The default on the newfs command is now '-i 2048' (1 inode per 2048 bytes of filesystem). The documented default under 4.0.x was 2048 but in reality the default was 4096. The result is that you wind up losing about 5% of your filesystems to the extra space required for the inodes. I've been creating new filesystems with 'newfs -i 4096'. The add_client command seems to randomly delete lines for /etc/exports. I've been backing up /etc/exports before running add_client to avoid this. Kyoto Common Lisp (akcl) doesn't work on SPARCserver 490's due to a change in the maximum DATA segment size. An (int)&extext in akcl/h/bsd.h has to be changed to (unsigned)&etext to fix the problem.
