これは、カスタムアクションをpolicykitに追加することで実行できます。rootでgeditを実行したい場合は、たとえばpkexec新しいファイルを作成する必要があります/usr/share/polkit-1/actions/org.freedesktop.policykit.gedit.policy。
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE policyconfig PUBLIC
"-//freedesktop//DTD PolicyKit Policy Configuration 1.0//EN"
"http://www.freedesktop.org/standards/PolicyKit/1/policyconfig.dtd">
<policyconfig>
<action id="org.freedesktop.policykit.pkexec.gedit">
<description>Run gedit program</description>
<message>Authentication is required to run the gedit</message>
<icon_name>accessories-text-editor</icon_name>
<defaults>
<allow_any>auth_admin</allow_any>
<allow_inactive>auth_admin</allow_inactive>
<allow_active>auth_admin</allow_active>
</defaults>
<annotate key="org.freedesktop.policykit.exec.path">/usr/bin/gedit</annotate>
<annotate key="org.freedesktop.policykit.exec.allow_gui">true</annotate>
</action>
</policyconfig>
最終的にpkexec gedit期待どおりに動作するはずです。
次のような例で説明されているマンページまたはリファレンスマニュアルをご覧ください。
$ man pkexec | grep -i ^Example -A 60
EXAMPLE
To specify what kind of authorization is needed to execute the program /usr/bin/pk-example-frobnicate as
another user, simply write an action definition file like this
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE policyconfig PUBLIC
"-//freedesktop//DTD PolicyKit Policy Configuration 1.0//EN"
"http://www.freedesktop.org/standards/PolicyKit/1/policyconfig.dtd">
<policyconfig>
<vendor>Examples for the PolicyKit Project</vendor>
<vendor_url>http://hal.freedesktop.org/docs/PolicyKit/</vendor_url>
<action id="org.freedesktop.policykit.example.pkexec.run-frobnicate">
<description>Run the PolicyKit example program Frobnicate</description>
<description xml:lang="da">Kør PolicyKit eksemplet Frobnicate</description>
<message>Authentication is required to run the PolicyKit example program Frobnicate (user=$(user), program=$(program), command_line=$(command_line))</message>
<message xml:lang="da">Autorisering er påkrævet for at afvikle PolicyKit eksemplet Frobnicate (user=$(user), program=$(program), command_line=$(command_line))</message>
<icon_name>audio-x-generic</icon_name>
<defaults>
<allow_any>no</allow_any>
<allow_inactive>no</allow_inactive>
<allow_active>auth_self_keep</allow_active>
</defaults>
<annotate key="org.freedesktop.policykit.exec.path">/usr/bin/pk-example-frobnicate</annotate>
</action>
</policyconfig>
and drop it in the /usr/share/polkit-1/actions directory under a suitable name (e.g. matching the namespace of
the action). Note that in addition to specifying the program, the authentication message, description, icon
and defaults can be specified. Note that occurences of the strings $(user), $(program) and $(command_line) in
the message will be replaced with respectively the user (of the form "Real Name (username)" or just "username"
if there is no real name for the username), the binary to execute (a fully-qualified path, e.g.
"/usr/bin/pk-example-frobnicate") and the command-line, e.g. "pk-example-frobnicate foo bar". For example, for
the action defined above, the following authentication dialog will be shown:
[IMAGE][2]
