The filer executes the commands in the
/etc/rc
file on the root volume at boot time to
configure the filer.
If your filer is licensed to run the CIFS protocol, the
/etc/rc
file must be present at boot
time for the CIFS protocol to be enabled. No CIFS-specific information is entered in
/etc/rc as a result of the
setup
procedure.
All the commands in the
/etc/rc
file are executable from the command line—there are
no commands that are restricted to being executed from within the /etc/rc file.

To make changes in the filer configuration that take effect every time the filer is
booted, perform the following steps:
1. Make a backup copy of the
/etc/rc
file.
2. Edit the /etc/rc file.
NOTE: Do not add CIFS commands in /etc/rc.

The
/home
directory is exported with
read and write permissions to all NFS
clients, and with root access to the
administration host.
Clients can mount directories after
the filer host name is added to the
filer
/etc/hosts
file or to the client’s
name server.
The svtx bit (also known as the sticky
bit) is set on the
/home
directory to
prevent users from deleting each
other’s files. This is a safe configura-
tion for networks that use UNIX
permissions to provide security for
network-accessible files. You can
clear the sticky bit with the
chmod
command.
The
/home
directory can be shared by
CIFS users as the home share imme-
diately after
setup
finishes.
Before users can read and write files
in the home share, you must follow
the procedures in the section, “Creat-
ing a Home Share for Each User,” in
Chapter 7.
By default, CIFS users can write and
delete their own files in
/home
. For
more information about access
rights, refer to the section,“Assigning
and Changing Access Rights,” in
Chapter 7.
