Within a .repo or
.service file, the name and URLs are subject to variable substitution.
Variables are e.g. useful for related repositories like packman (http://ftp.gwdg.de/pub/linux/packman/suse/$releasever
), which shall always fit the installed distribution, even after a distribution upgrade. To help performing a distribution upgrade, the value of $releasever
can be overwritten in zypper using the --releasever
global option. This way you can easily switch all repositories using $releasever
to the new version (provided the server layouts did not change and new repos are already available).
The variable expander also supports shell like definition of default and alternate values.
$arch
- The system's CPU architecture.$basearch
- The base architecture of the system. For example, iX86 machines have a base architecture of i386
, while AMD64 and Intel64 have x86_64
.$releasever
- The version of your openSUSE or SUSE Linux. The value is obtained from the /product/version
XML-node in /etc/products.d/baseproduct
.$releasever_minor
$releasever_major
- $releasever_major
will be set to the leading portion up to (but not including) the 1st dot; $releasever_minor
to the trailing portion after the 1st dot. If there's no dot in $releasever
, $releasever_major
is the same as $releasever
and $releasever_minor
is empty.A custom repository variable is defined by creating a file in /etc/zypp/vars
.d. The variable name equals the file name. The files first line (up to but not including the newline character) defines the variables value. Valid variable(file) names consist of alphanumeric chars and '_' only.
Variable substitution within an URIs authority [requires 'libzypp(repovarexpand) >= 1.1'] is limited to host
and port
. Bash style definition of default and alternate values is not supported. No variables can be used in an URIs scheme
, user
and password
.
