mount unitの一覧表示をする場合は以下のコマンドを実行します。
systemctl list-units -t mount
上記コマンドの実行結果例を記します。
$ systemctl list-units -t mount UNIT LOAD ACTIVE SUB DESCRIPTION -.mount loaded active mounted / boot.mount loaded active mounted /boot dev-hugepages.mount loaded active mounted Huge Pages File System dev-mqueue.mount loaded active mounted POSIX Message Queue File Syst proc-fs-nfsd.mount loaded active mounted NFSD configuration filesystem sys-kernel-config.mount loaded active mounted Configuration File System sys-kernel-debug.mount loaded active mounted Debug File System var-lib-nfs-rpc_pipefs.mount loaded active mounted RPC Pipe File System <snip>
systemctl list-units -t swap
上記コマンドの実行結果例を記します。
$ systemctl list-units -t swap UNIT LOAD ACTIVE SUB DESCRIPTION dev-dm\x2d0.swap loaded active active /dev/dm-0 LOAD = Reflects whether the unit definition was properly loaded. ACTIVE = The high-level unit activation state, i.e. generalization of SUB. SUB = The low-level unit activation state, values depend on unit type. 1 loaded units listed. Pass --all to see loaded but inactive units, too. To show all installed unit files use 'systemctl list-unit-files'.
以上、systemdのservice unit一覧を確認する方法でした。
