Many system files, such as the /etc/fstab file, have been replaced and do not exist under the Solaris 7 operating environment. Information from these files must be extracted and manually converted in the Solaris 7 environment. See Appendix D, System Files Reference Table, to examine SunOS release 4 files for changes.
Do not restore operating system executable files (such as system commands in /usr/bin) from the SunOS release 4 system to your system after installing the Solaris 7 software.
/etc/uucp - There have been some changes to the UUCP system. The Config, Grades, and Limits files are new in the Solaris 7 operating environment. The files Devconfig, Devices, Dialcodes, Dialers, Permissions, Poll, Sysfiles, and systems are the same in the Solaris 7 operating environment as they were in the SunOS release 4 software. These files can be merged together. There are also several SunOS release 4 files that are not used in the Solaris 7 operating environment.
/etc/group - The basic format of this file is the same as it was in the SunOS 4.1 and SunOS 4.1.x releases. However, previous releases used a group entry beginning with a plus sign (+) or minus sign (-) to selectively incorporate entries from NIS maps for group. See the group(4) man page if that compatibility is needed under the Solaris 7 operating environment.
/etc/exports - File systems to be shared on the network under the Solaris 7 operating environment use the /etc/dfs/dfstab file instead of /etc/exports. The format of entries in this file is like the following.
share -F fstype -o options -d "text" pathname resource
See the dfstab(4) man page for additional information.
dev raw_dev mnt_pt fs_type fsck_pass auto_mnt mnt_option
Refer to the vfstab(4) man page for additional information.
/etc/passwd - The format of the passwd file is the same as that under the SunOS release 4 software. However, user passwords are now stored in the /etc/shadow file. Refer to the passwd(4) and shadow(4) man pages for additional information.
/etc/ttytab - Under the SunOS release 4 system, ttytab was used to control serial ports and the characteristics of the terminals on those serial lines. Under the Solaris 7 operating environment, the Service Access Facility is used to configure this capability.
/etc/printcap - Under the Solaris 7 operating environment, printers are configured using the SunOS release 5.7 LP print service. See System Administration Guide, Volume I for additional information.
