NAME
admin - installation defaults file
DESCRIPTION
admin is a generic name for an ASCII file that defines
default installation actions by assigning values to instal-
lation parameters. For example, it allows administrators to
define how to proceed when the package being installed
already exists on the system.
/var/sadm/install/admin/default is the default admin file
delivered with this release. The default file is not writ-
able, so to assign values different from this file, create a
new admin file. There are no naming restrictions for admin
files. Name the file when installing a package with the -a
option of pkgadd(1M). If the -a option is not used, the
default admin file is used.
Each entry in the admin file is a line that establishes the
value of a parameter in the following form:
param=value
All of the parameters listed below can be defined in an
admin file, but it is not required to assign values to all
of these. If a value is not assigned, pkgadd(1M) asks the
installer how to proceed.
The valid parameters and their possible values are shown
below except as noted. They can be specified in any order.
Any of these parameters (except the mail and proxy parame-
ters) can be assigned the value ask, which means that, when
the parameter is reached during the installation sequence,
the installer is notified and asked to supply instructions
(see NOTES).
basedir
Indicates the base directory where relocatable packages
are to be installed. If there is no basedir entry in the
file, the installer will be prompted for a path name, as
if the file contained the entry basedir=ask. This param-
eter can also be set to default (entry is
basedir=default). In this instance, the package is
installed into the base directory specified by the
BASEDIR parameter in the pkginfo(4) file.
mail

File Formats admin(4)
Defines a list of users to whom mail should be sent fol-
lowing installation of a package. If the list is empty,
no mail is sent. If the parameter is not present in the
admin file, the default value of root is used. The ask
value cannot be used with this parameter.
runlevel
Indicates resolution if the run level is not correct for
the installation or removal of a package. Options are:
nocheck Do not check for run level.
quit Abort installation if run level is not
met.
conflict
Specifies what to do if an installation expects to
overwrite a previously installed file, thus creating a
conflict between packages. Options are:
nocheck Do not check for conflict; files in con-
flict will be overwritten.
quit Abort installation if conflict is
detected.
nochange Override installation of conflicting
files; they will not be installed.
setuid
Checks for executables which will have setuid or setgid

bits enabled after installation. Options are:
nocheck Do not check for setuid executables.
quit Abort installation if setuid processes
are detected.
nochange Override installation of setuid
processes; processes will be installed
without setuid bits enabled.
action
Determines if action scripts provided by package
developers contain possible security impact. Options
are:
nocheck Ignore security impact of action
scripts.
quit Abort installation if action scripts may
have a negative security impact.
partial
Checks to see if a version of the package is already
partially installed on the system. Options are:
nocheck Do not check for a partially installed
package.
quit Abort installation if a partially
installed package exists.

instance
Determines how to handle installation if a previous ver-
sion of the package (including a partially installed
instance) already exists. Options are:
quit Exit without installing if an instance
of the package already exists (does not
overwrite existing packages).
overwrite Overwrite an existing package if only
one instance exists. If there is more
than one instance, but only one has the
same architecture, it overwrites that
instance. Otherwise, the installer is
prompted with existing instances and
asked which to overwrite.
unique Do not overwrite an existing instance of
a package. Instead, a new instance of
the package is created. The new instance
will be assigned the next available
instance identifier.
idepend
Controls resolution if the package to be installed
depends on other packages and if other packages depend
on the one to be installed. Options are:
nocheck Do not check package dependencies.
quit Abort installation if package dependen-
cies are not met.

rdepend
Controls resolution if other packages depend on the
package to be removed. Also determines behavior if
registered products components to be removed. See
libwsreg(3LIB) and prodreg(1M) for a definition of pro-
duct components. Options are:
nocheck Do not check package or product depen-
dencies.
quit Abort removal if package or product
dependencies are not met.
space
Controls resolution if disk space requirements for pack-
age are not met. Options are:
nocheck Do not check space requirements (instal-
lation fails if it runs out of space).
quit Abort installation if space requirements
are not met.
authentication
Controls resolution when a datastream package with sig-
nature is to be installed. Options are:
nocheck Do not verify package signature. This
also disables the use of the Online Cer-
tificate Status Protocol (OCSP) to vali-
date the package's signing certificate.

quit Abort installation if package signature
cannot be verified.
networktimeout
Number of seconds to wait before giving up a network
connection when downloading a package. This entry must
be a positive integer. If not present, the default value
of 60 is used.
networkretries
Number of times to retry a failed network connection
when downloading a package. This entry must be a posi-
tive integer. If not present, the default value of 5 is
used.
keystore
Location of trusted certificates used when downloading
packages over SSL and when verifying signatures on pack-
ages. This is the base directory of the certificate
location for trusted certificates used when validating
digital signatures on packages. For example, if this
setting is /var/sadm/security, then pkgadd will use
/var/sadm/security/pkgadd/truststore, then
/var/sadm/security/truststore when searching for trusted
certificates. See KEYSTORE LOCATIONS and KEYSTORE AND
CERTIFICATE FORMATS in pkgadd(1M) for details on certi-
ficate store format and usage.
proxy
The default proxy to use when installing packages from
the network. Currently, only HTTP or HTTPS proxies are
supported. If this field is blank or nonexistent, then
no proxy will be used.
rscriptalt=root | noaccess
Determines the user that will run request scripts. This
parameter can have either of the values described below.
SunOS 5.10 Last change: 20 Dec 2004 6
File Formats admin(4)
See pkgadd(1M) for details on the conditions under which
this parameter is useful.
root
Run request script as user install, if such a user
exists, with the privileges of that user. Otherwise,
run script as user root, with UID equal to 0 and
with all/zone privileges. (See zones(5).)
noaccess
Run request script as user install, if such a user
exists, with the privileges of that user. Otherwise,
run script as user noaccess, with the basic
privileges of the unprivileged user noaccess.
If this parameter is not present or has a null value,
the user noaccess is assumed. Likewise, if this parame-
ter is set to anything other than the values described
here, a warning is issued, and noaccess is assumed.
rscriptalt is not present in the default admin file,
/var/sadm/install/admin/default. In this case, request
scripts are run as the user noaccess.
EXAMPLES
Example 1: Default admin File
The default admin file, named default, is shipped with
user-, group-, and world-read privileges (444). Its contents
are as follows:
mail=
instance=unique
partial=ask
runlevel=ask
idepend=ask
rdepend=ask
space=ask
setuid=ask
conflict=ask
action=ask
basedir=default
authentication=quit
networktimeout=10
networkretries=3

tion when no other admin file is specified.

NOTES
The value ask should not be defined in an admin file that
will be used for non-interactive installation (because, by
definition, there is no installer interaction). Doing so
causes installation to fail at the point when input is
needed.
