Files to Convert

Many system files, such as the /etc/fstab file, have been replaced and do not exist under the Solaris 2.6 operating environment. Information from these files must be extracted and manually converted in the Solaris 2.6 environment. See Appendix D, System Files Reference Table, to examine SunOS release 4.x files for changes.

Do not restore operating system executable files (such as system commands in /usr/bin) from the SunOS release 4.x system to your system after installing the Solaris 2.6 software.

You must change the following files before merging the data onto the Solaris 2.6 system:

• /etc/uucp - There have been some changes to the UUCP system. The Config, Grades, and Limits files are new in the Solaris 2.6 operating environment. The files Devconfig, Devices, Dialcodes, Dialers, Permissions, Poll, Sysfiles, and systems are the same in the Solaris 2.6 operating environment as they were in the SunOS release 4.x software. These files can be merged together. There are also several SunOS release 4.x files that are not used in the Solaris 2.6 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 2.6 operating environment.

• /etc/netgroup - There is no /etc/netgroup file in the SunOS release 5.6 environment.

• /etc/exports - File systems to be shared on the network under the Solaris 2.6 operating environment use the /etc/dfs/dfstab file instead of /etc/exports. The format of entries in this file follows.

share -F fstype -o options -d "text" pathname resource

See the dfstab(4) man page for additional information.

• /etc/fstab - File systems to be mounted under the Solaris 2.6 operating environment use the /etc/vfstab file instead of /etc/fstab. The format of entries in the /etc/vfstab file follows.

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.x 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/sendmail.cf - The format of sendmail.cf is the same as that under the SunOS release 4.x structure. The location of the file is now /etc/mail/sendmail.cf.

• /etc/ttytab - Under the SunOS release 4.x system, ttytab was used to control serial ports and the characteristics of the terminals on those serial lines. Under the Solaris 2.6 operating environment, the Service Access Facility is used to configure this capability.

• /etc/printcap - Under the Solaris 2.6 operating environment, printers are configured using the SunOS release 5.6 LP print service. See System Administration Guide for additional information.
