Other configuration files are different on ULTRIX and DIGITAL UNIX
systems. For example, the DIGITAL UNIX system does not have the
following configuration files:
• crontab
Instead of using an /etc/crontab file, the directory
/usr/var/spool/cron/crontabs contains a number of files that the
cron daemon uses to start facilities. For more information, see cron
(8).
• rc.local
On a DIGITAL UNIX system, the system initialization functions
performed by the ULTRIX /etc/rc.local file are provided by the
/etc/inittab file and the shell scripts in the /sbin/init.d
directory. For more information about system initialization, see the
System Administration manual.
• gettytab
The /etc/gettytab file is obsolete and has been replaced by
/etc/gettydefs. To allow communication with systems using
nonstandard parameters, copy one of the existing gettydefs entries
and edit the copy as required to provide the parameters you need. See
gettydefs
(4) for specific file format information.
• ttys
The function of the /etc/ttys file is changed. DIGITAL UNIX systems
use the /etc/ttys file to control root access by marking which lines
are secure. The /etc/inittab file is used to configure terminal lines.
You might want to save your ULTRIX /etc/ttys file for information
on the configurations of specific terminal lines, but the format of the
/etc/inittab file is very different. See inittab
(4) for specific file
format information.
Information about the differences between most other ULTRIX and
DIGITAL UNIX customization files is in this chapter. For information
about creating and modifying those files, see the Network Administration
manual and the System Administration manual.
