A profile is a text file that defines how to install the Solaris software on a system. A profile defines elements of the installation, for example, the software group to install. Every rule specifies a profile that defines how a system is to be installed. You can create different profiles for every rule or the same profile can be used in more than one rule.
A profile consists of one or more profile keywords and their values. Each profile keyword is a command that controls one aspect of how the JumpStart program is to install the Solaris software on a system. For example, the following profile keyword and value specify that the JumpStart program install the system as a server:
If you created the JumpStart directory by using the procedures that are presented in Creating a Profile Server for Networked Systems or Creating a Profile Diskette for Standalone Systems, sample profiles are already located in the JumpStart directory.
One keyword per line
The root_device keyword if the systems that are being upgraded by the profile contain more than one root (/) file system that can be upgraded
A profile can contain the following:
One or more blank lines
Use a text editor to create a text file. Name the file descriptively. Or, open a sample profile in the JumpStart directory that you created.
Ensure that the name of the profile reflects how you intend to use the profile to install the Solaris software on a system. For example, you might name the profiles basic_install, eng_profile, or user_profile.
Add profile keywords and values to the profile.
For a list of profile keywords and values, see Profile Keywords and Values.
Profile keywords and their values are case sensitive.
Save the profile in the JumpStart directory.
Ensure that root owns the profile and that the permissions are set to 644.
Test the profile (optional).
Testing a Profile contains information about testing profiles.
The following examples of profiles show how to use different profile keywords and profile values to control how the Solaris software is installed on a system. Profile Keywords and Values contains a description of profile keywords and values.
# profile keywords profile values # ----------------- ----------------- install_type initial_install1 system_type standalone2 partitioning default3 filesys any 512 swap # specify size of /swap cluster SUNWCprog4 package SUNWman delete5 cluster SUNWCacc
The install_type keyword is required in every profile.
The system_type keyword defines that the system is to be installed as a standalone system.
The file system slices are determined by the software to be installed with the value default. The size of swap is set to 512 Mbytes and is installed on any disk, value any.
The Developer Solaris Software Group, SUNWCprog, is installed on the system.
If the standard man pages are mounted from the file server, s_ref, on the network, the man page packages are not to be installed on the system. The packages that contain the System Accounting utilities are selected to be installed on the system.
# profile keywords profile values # ---------------- ------------------- install_type initial_install system_type standalone partitioning explicit1 filesys c0t0d0s0 auto / filesys c0t3d0s1 auto swap filesys any auto usr cluster SUNWCall2
The file system slices are determined by the filesys keywords, value explicit. The size of root (/) is based on the selected software, value auto, and is installed on c0t0d0s0. The size of swap is set to the necessary size and is installed on c0t3d0s1. usr is based on the selected software and the installation program determines where usr is installed, based on the value any.
The Entire Solaris Software Group, SUNWCall, is installed on the system.
# profile keywords profile values # ---------------- ------------------- install_type initial_install system_type standalone fdisk c0t0d0 0x04 delete1 fdisk c0t0d0 solaris maxfree2 cluster SUNWCall3 cluster SUNWCacc delete4
All fdisk partitions of type DOSOS16 (04 hexadecimal) are deleted from the c0t0d0 disk.
A Solaris fdisk partition is created on the largest contiguous free space on the c0t0d0 disk.
The Entire Distribution software group, SUNWCall, is installed on the system.
The system accounting utilities, SUNWCacc, are not to be installed on the system.
# profile keywords profile values # ---------------- ------------------- install_type upgrade1 root_device c0t3d0s22 backup_media remote_filesystem timber:/export/scratch3 layout_constraint c0t3d0s2 changeable 1004 layout_constraint c0t3d0s4 changeable layout_constraint c0t3d0s5 movable package SUNWbcp delete5 package SUNWxwman add6 cluster SUNWCacc add locale de7
The profile upgrades a system by reallocating disk space. In this example, disk space must be reallocated because some file systems on the system did not have enough space for the upgrade.
The root file system on c0t3d0s2 is upgraded.
A remote system that is named timber is to be used to back up data during the disk space reallocation. For more backup-media keyword values, see backup_media Profile Keyword.
The layout_constraint keywords designate that auto-layout can perform the following when auto-layout attempts to reallocate disk space for the upgrade.
Change slices 2 and 4. The slices can be moved to another location and the size can be changed.
Move slice 5. The slice can be moved to another location but its size cannot change.
The binary compatibility package, SUNWbcp, is not installed on the system after the upgrade.
The code ensures that the X Window System man pages and the System Accounting Utilities are to be installed if they are not already installed on the system. All packages already on the system are automatically upgraded.
The German localization packages are to be installed on the system.
install_type flash_install1 archive_location http installserver /flasharchive/solaris9archive2 partitioning explicit3 filesys c0t1d0s0 4000 / filesys c0t1d0s1 512 swap filesys c0t1d0s7 free /export/home
The profile installs a Solaris Flash archive on the clone system. All files are overwritten as in an initial installation.
The Solaris Flash archive is retrieved from an HTTP server.
The file system slices are determined by the filesys keywords, value explicit. The size of root (/) is based on the selected software and is installed on c0t1d0s0. The size of swap is set to the necessary size and is installed on c0t1d0s1. /export/home is based on the selected software and is installed on c0t1d0s7.
In the following example, the profile indicates that the custom JumpStart program retrieves the Solaris Flash archive from an NFS server. The flash_update keyword indicates that this is a differential archive. A differential archive installs only the differences between two system images.
install_type flash_update1 archive_location nfs installserver:/export/solaris/flasharchive/solaris9archive2 no_master_check3 root_device c0t0d0s64
The profile installs a Solaris Flash differential archive on the clone system. Only files that are specified by the archive are installed.
The Solaris Flash archive is retrieved from an NFS server.
The clone system is not checked for a valid system image. A valid system image would have been built from the original master system.
Specifies that the root file system on c0t0d0s6 is to be updated.
