SYSUPGRADE.CONF(5) BSD File Formats Manual SYSUPGRADE.CONF(5)NAMEsysupgrade.conf — configuration file to control NetBSD system upgrades
DESCRIPTION
Configuration files for sysupgrade(8) are simple shell scripts that set,
or explicitly clear, a collection of known configuration variables.
The following configuration variables are recognized:
AUTOCLEAN Whether to automatically delete the downloaded files or not
as part of the ‘auto’ command.
If you set ETCUPDATE to false, you will probably want to
disable autocleaning. This will let you run the
‘etcupdate’ command on your own at a later stage reusing
the same distribution sets used to upgrade the system.
Default: yes.
CACHEDIR Path to the local directory into which distribution sets
are temporarily fetched while applying a system upgrade.
Note that all sysupgrade.conf commands that need access to
the distribution sets (pretty much all of them) will read
from this directory. If you plan on issuing different
upgrade steps at different times, this directory should
persist across the different executions.
Default: /var/cache/sysupgrade
DESTDIR Path to the root of the system to be upgraded. This is
prepended to all other paths affected by sysupgrade(8) and
can be used to perform upgrades of non-live systems or for
testing purposes.
Default: not set (which means / is affected).
ETCUPDATE Whether to run etcupdate(8) as part of an automated
upgrade. You may want to disable this because this is the
only interactive step in the upgrade process.
If set to false, the ‘auto’ subcommand will skip this step.
In this case, you are also recommended to set AUTOCLEAN to
‘no’ so that you are not required to redownload the distri‐
bution files just to run etcupdate(8) later.
Default: yes.
KERNEL Name of the kernel to install. There must be a
‘netbsd-<KERNEL>.gz’ file in the release directory matching
this name.
If this is set to the magic value ‘AUTO’, sysupgrade(8)
will attempt to automatically determine the name of the
current kernel by using config(1) on <DESTDIR>/netbsd. If
the guessing fails, an error is raised to prevent
installing a mismatching kernel.
Default: AUTO.
POSTINSTALL_AUTOFIX
Whitespace-separated list of postinstall(8) checks that
will be unconditionally fixed as part of an upgrade.
It is recommended that you include ‘obsolete’ in this list
at the very least: this check often fails because it is
common for newer releases to drop existing files, and fix‐
ing it should be harmless. Note that old shared libraries
are never cleaned by this check, so existing third-party
binaries should not stop working even after auto-fixing
this check.
Default: empty.
RELEASEDIR Location of the release directory (which must hold a
binary/sets/ subdirectory). This can be either a local
path or a URL.
If the location is a URL, any of the HTTP, FTP or SSH pro‐
tocols are supported. In the case of SSH, the URL takes
the form: ‘ssh://[user[:password]@]<host>/<absolute_path>’,
which is different to the syntax accepted by scp(1).
Default: not set.
SETS Whitespace-separated list of distribution sets to install.
If this is set to the magic value ‘AUTO’, the list of sets
is determined from the files in <DESTDIR>/etc/mtree.
This list cannot include any ‘kern-*’ sets; the kernel to
be installed is determined by the KERNEL variable.
The presence of any configuration sets (such as ‘etc’ or
‘xetc’) in this list enables the etcupdate and postinstall
steps in the automated upgrade procedure.
The presence of a modules set enables the modules step in
the automated upgrade procedure.
Default: AUTO.
