You can use systemd to instantiate a service on device discovery (or run a daemon that listens to events from udev on old init systems). Check how bluetooth, cups printers, usbmux, ... is handled: TAG+="systemd", ENV{SYSTEMD_WANTS}="configure-printer@usb-$env{BUSNUM}-$env{DEVNUM}.service" TAG+="systemd", ENV{SYSTEMD_WANTS}+="bluetooth.target" TAG+="systemd", ENV{SYSTEMD_WANTS}="usbmuxd.service" Kay
Well, Things pretend to be simple seems to be not simple After few hours of fighting with issue I have to ask for help.
udev rule: SUBSYSTEM=="block", KERNEL=="sd[c-z][0-9]", GOTO="begin" GOTO="end" LABEL="begin" ACTION=="add", GOTO="begin_add" ACTION=="remove", GOTO="begin_remove" GOTO="end" LABEL="begin_add" SYMLINK+="usbhd-%k", GROUP="root" ENV{ID_FS_LABEL_ENC}="usbhd-%k" IMPORT{program}="/sbin/blkid -o udev -p $tempnode"ENV{ID_FS_LABEL_ENC}==".myth.backup", ENV{MOUNT_DIR}="/media/$env{ID_FS_LABEL_ENC}", RUN+="/bin/mkdir -p $env{MOUNT_DIR}", RUN+="/bin/mount -t auto -o rw,noauto,noatime /dev/%k $env{MOUNT_DIR}" ENV{ID_FS_LABEL_ENC}==".myth.backup", TAG+="systemd", ENV{SYSTEMD_WANTS}="ext-usb-backup.service"
GOTO="end" service file: [Unit] Description=MythtTV ExtUSB Backup Helper [Service] ExecStart=/usr/local/bin/run-backup.sh Type=forking GuessMainPID=false RemainAfterExit=no Issue: it works with:ENV{ID_FS_LABEL_ENC}==".myth.backup", RUN+="/usr/bin/systemctl start ext-usb-backup.service"
but not works with:ENV{ID_FS_LABEL_ENC}==".myth.backup", TAG+="systemd", ENV{SYSTEMD_WANTS}="ext-usb-backup.service"
(With TAG+ENV approach udev behaves like line with TAG+ENV is non-existing: no any error nor any sign it is parsed)
Where the hell issue is ?log for ENV{ID_FS_LABEL_ENC}==".myth.backup", RUN+="/usr/bin/systemctl start ext-usb-backup.service"
