root_archive(1M) System Administration Commands root_archive(1M)NAMEroot_archive - manage bootable miniroot archives
SYNOPSIS
/boot/solaris/bin/root_archive pack archive root
/boot/solaris/bin/root_archive unpack archive root
/boot/solaris/bin/root_archive packmedia solaris_image root
/boot/solaris/bin/root_archive unpackmedia solaris_image root
DESCRIPTION
The root_archive utility is used to manipulate boot archives and the
bootable miniroot(s) in a Solaris install image. The utility can pack
and unpack boot archives and image miniroots. Both ufs and hsfs
(iso9660) format archives can be unpacked, although only ufs format is
generated when packing.
For normal, boot-related system administration, bootadm(1M) is recom‐
mended. root_archive's primary purpose is to enable OEMs to add or
update a driver or other component on the Solaris install media.
A miniroot and a boot archive is closely associated with the release it
is intended to boot. To ensure that the tools and system services used
to construct the miniroot match, miniroot manipulation must be per‐
formed only on a system running the same release for which the miniroot
is intended to install.
SUBCOMMANDS
The root_archive command has the following subcommands:
pack archive root Pack the contents of the root directory into the
boot archive archive.
unpack archive root
Unpack the contents of the boot archive named archive to the direc‐
tory named root.
packmedia solaris_image root
Create and pack the miniroot(s) in solaris_image from the contents
of the directory named root.
unpackmedia solaris_image root
Unpack the contents of the miniroot(s) in solaris_image to the
directory named root.
The contents of a miniroot are constructed to need the requirements of
the release. When unpacking a miniroot, all the contents of the mini‐
root(s) are unpacked. When packing a miniroot, the source directory
must contain all the necessary components with which to construct a
miniroot. In general, this can only be achieved by first unpacking an
existing miniroot.
EXAMPLES
Example 1 Unpacking the Miniroots in a Solaris x86 Install Image
The following command unpacks the miniroots in a Solaris image to the
root directory in /export/release/latest.
# root_archive unpackmedia \
/export/nv/solarisdvd.nvx_dvd/latest /export/release/latest/root
In the preceding, /export/nv/solarisdvd.nvx_dvd/latest represents a
path to a Solaris x86 install image and /export/release/latest/root is
a directory that will be purged or created, as necessary.
Example 2 Packing the Miniroots in a Solaris x86 Install Image
The following command creates and packs the miniroot(s) in a Solaris
image from the contents of the directory /export/release/latest/root.
# root_archive packmedia \
/export/nv/solarisdvd.nvx_dvd/latest /export/release/latest/root
EXIT STATUS
The following exit values are returned:
0 The command completed successfully.
1 The command exited due to an error.
