I guess another option would just be to write out a flag file into /run tree when you do the first call. First call the file won't exist, all subsequent calls it will. That might fit better with a scripted solution than calling out to an exec, but YMMV.

[systemd-devel] Detect if a script runs during bootup
Hi, is there an easy way to figure out if a LSB script in /etc/init.d/ is called during bootup by systemd? I need to distinguish the first execution during boot from subsequent calls (cron, manually etc.). It seems that /sbin/runlevel returns "unknown" during bootup, but I'm not sure if this reliable or not. cu, Frank -- Dipl.-Inform. Frank Steiner Web: http://www.bio.ifi.lmu.de/~steiner/ Lehrstuhl f.

I would suggest splitting the "on boot only" part into separate unit, with RemainAfterExit=true. The main part should require boot-only part.

There's no distinction between "boot" and "subsequnct calls": what if boot takes a bit longer and cron calls the script during boot?

The LSB script is called several times with different parameters. It always sources another script. In this script I need to perform an action only at the first time this script is sourced during the boot process. Thus having a flag letting me know that I'm inside the boot sequence would be enough to have an unique situation for performing this special action. If I was able to work with systemd unit files, I could perfectly do what I want, but I'm stuck with this LSB file. Isn't there an easy way to figure out if this script is running inside the boot process? Some variable set or not yet set? cu, Frank -- Dipl.-Inform.
