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 ?
