AD: Manifests from the standard directory trees /lib/svc/manifest and /var/svc/manifest are processed during system boot and anytime an administrator or program runs:

$ svcadm restart manifest-import

C: svccfg

apply subcommand

If the argument is a service profile or manifest, apply the configuration to the admin layer of the SMF repository. Services, instances, property groups, and properties will be created as necessary.

E: import [-V] [file | directory]

svccfg import on a file in a system-managed filesystem location (subdirectories of /lib/svc/manifest and /var/svc/manifest) invokes: svcadm restart manifest-import.

Placing your manifests in a system-managed location and invoking svcadm restart manifest-import to import them is the recommended practice.

svccfg import on files in other locations imports their properties as administrative customization into the admin layer. It is equivalent to:

svccfg apply [file | directory]

Incorrect:

not B: Manifests are processed in two different phases during boot.

The service svc:/system/early-manifest-import:default, a pseudo service, is responsible for the first manifest processing. This service processes only manifests from the /lib/svc/manifest directory tree before svc.startd(1M) initializes any services thus enabling services delivered in /lib/svc/manifest to always start with their most updated definition. Since this is a pseudo service, svcadm(1M) commands are ignored though svcs(1) can be used to observe status and get log file information.

The svc:/system/manifest-import:default service handles the second manifest processing and imports manifest files from both /lib/svc/manifest and /var/svc/manifest directory trees, in that respective order.

Note:

* The Trusted Solaris environment provides audit classes including:

ss - Change system state

no - Invalid class

lo - Login or logout

* always-audit

Lists the audit classes that are audited for this user. Modifications to the system-wide classes are prefixed by a caret (^). Classes that are added to the system-wide classes are not prefixed by a caret.

never-audit

Lists the audit classes that are never audited for the user, even if these audit events are audited system-wide. Modifications to the system-wide classes are prefixed by a caret (^).

* Process preselection mask – A combination of the system-wide audit mask and the user-specific audit mask, if a user audit mask has been specified. When a user logs in, the login process combines the preselected classes to establish the process preselection mask for the user's processes. The process preselection mask specifies whether events in each audit class are to generate audit records.

The following algorithm describes how the system obtains the user's process preselection mask:

(system-wide default flags + always-audit-classes) - never-audit-classes

* getent user_attr

getent

- get entries from administrative database

getent gets a list of entries from the administrative database specified by database. The information generally comes from one or more of the sources that are specified for the database in /etc/nsswitch.conf.

Example. Displaying Administratively Customized Properties (here only admin layer is displayed with –l)

The following command uses SMF layers to display administratively customized properties.

example% svcprop -p config -l admin svc:/network/dns/client

(A) config/domain astring admin my.domain.com

(D) config/nameserver net_address admin 10.22.33.44 10.44.33.11

Note:

* config/nameserver refers to the Solaris DNS server.

/ The nameserver keyword specifies DNS servers to query using IP address.

Example:

The /etc/resolv.conf file contains configuration directives for the DNS resolver. The following resolv.conf example shows two name servers and three search suffixes:

domain nj.bigcorporation.com

nameserver 192.168.10.11

nameserver 192.168.20.88

* The svcprop utility prints values of properties in the service configuration repository. Properties are selected by -p options and the operands
