[systemd-devel] systemd195: issue with udev launched script

Thu, 15 Nov 2012 11:13:13 -0800 

Hi *

Sometime ago upgraded my ArchLinux (kernel3.3.8) server to systemd195.
Today I discovered that my backup procedure fails. It was working OK with previous systemd. Forgive me if this forum is wrong place to ask such questions, but as udev is now part of systemd - I decided to ask here... 
I know that long tasks launched by udev should be detached.
Maybe some merciful soul help me with finding error in following approach:
(maybe there is better way do to launching scripts on USN attach ?)

Goal:
attaching USB-HD should launch backup script.

Solution:
udev rule mounting hd fs and launching script.

udev rule is following:
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", GOTO="backup_begin"
  ENV{ID_FS_LABEL_ENC}=="USB-Movies*", GOTO="rips_begin"
  GOTO="user_storage_begin"

LABEL="backup_begin"
  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}"
  RUN+="/usr/bin/sleep 15"
  RUN+="/usr/local/bin/run-backup.sh &"
  GOTO="end"

Issue:
Script starts but seems to be killed by udev :-(

relevant kernel log:
