I keep seeing [Install] WantedBy=multi-user.target or [Install] WantedBy=sysinit.target or some such Description of targets is in man systemd.special. I have for example a need to mount stuff (via a mount unit ) then to create directories and copy stuff to them I dont know if these '/bin/mkdir' and '/bin/cp' tasks can be done under '[Install]' They cannot be in mount. There are few way to accomplish what you want, but without details I can provide only vague directions. You need to create unit for your work. You can stuff mkdir into ExecStartPre and cp into ExecStart; you have to make your unit Require the mount unit (or go with the automounter); activation of your work unit should trigger mount. There are few details to work out, like for example usage of PartOf. Ib brief, I dont know what [Install] is for, --what goes under it? --when it is used ? --or not used etc ? --and I cant locate a manpage to explain it. I would be grateful if someone could send me the appropriate URL for 'Install' manpage and or explain what it is and how it is used. Start with man systemd.unit and search for [Install]. All four directives are described there. The information is used by systemctl enable command to create appropriate symlinks.

Thanks for your reply I take the opportunity to layout in more detail what my problem is and hopefully you and others will provide guidance:- I want to translate the followingfrom a typical init scipt to systemd. ## /bin/mount \ -m $someMode \ -t someType \ -o opt1,opt2,opt3 \ someDIR /somewhereInFS /bin/mkdir \ --mode $someMode $someDIR/otherDIR /bin/cp -a someStuff $someDIR/otherDIR # My first approach is to use a so-called service file like so [Unit] Description=Mounting and copying stuff [Service] ExecStart=/bin/mount \ -m $someMode \ -t someType \ -o opt1,opt2,opt3 \ someDIR /somewhereInFS ExecStart=/bin/mkdir \ --mode $someMode $someDIR/otherDIR ExecStart=/bin/cp -a someStuff $someDIR/otherDIR ## However I would like to use so called mount units and with this approach this is the furtherst I get:- [Unit] Description=Mounting somewhereInFS #After=dont know what to put here? #Before=dont know what to put here? [Mount] What=someDIR Where=/somewhereInFS Type=someType Options=opt1,opt2,opt3 DirectoryMode=$someMode I am then stuck I dont know where to put the last two commands namely:- # ExecStart=/bin/mkdir \ --mode $someMode $someDIR/otherDIR and ExecStart=/bin/cp -a someStuff $someDIR/otherDIR #-- do I have to create a service file for these and if so how do I ensurethe mount unit is exicuted before this service is called? ( Remark::- this is a learnig exercise And using fstab is not in such an instance an option ) Thanks in advance sincerely luxInteg ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
