我也想知道我的Ubuntu安装上可能是什么,所以我看了一下服务文件/lib/systemd/system/click-system-hooks.service
:
[Unit]
Description=Run Click system-level hooks
Documentation=man:click(1)
[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/usr/bin/click hook run-system
Restart=no
[Install]
WantedBy=multi-user.target
因此,它负责调用/usr/bin/click hook run-system
。根据其手册页,单击是
Ubuntu Touch的软件包管理工具
和参数hook run-system
均值
Run all system-level hooks for all installed Click packages. This is useful when starting up from images with preinstalled packages which may not have had their system-level hooks run properly when building the image.
最后,如果您不运行Ubuntu Touch,则可以通过禁用该服务,sudo systemctl disable click-system-hooks.service
或者从系统中完全删除click。
对于我来说,我怀疑它是随包附带的,unity8-desktop-session
它间接取决于click,因此必须安装。
