[systemd-devel] how can I add a boot parameter to a app which depend on kernel boot option

[Umut Tezduyar Lindskog]

Hi Xiong

You can have a script that reads the  /proc/cmdline and then calls
exec with your app.

ExecStart=/your/custom/scipt

cat /your/custom/script:

# Do what ever you want, figure out parameters

# Start your application
exec myapp --parameter=xyz
