It's already been pointed out that you'll need to modify the init 
script, but just to make clear why that is the case, I thought it should 
be pointed out that "ulimit" is a bash built-in command. When you run 
"ulimit -s 10240" you're not modifying the system, as a whole.  You're 
only modifying that shell's environment and any child process that you 
start from that shell.  Not only does the command not survive a reboot, 
it doesn't persist between logins.

And that's one of the better features of systemd.  Because services are 
always started by systemd, they don't inherit environment, or process 
limits, or SELinux context from a login shell.  If they start correctly 
interactively, via systemctl, they'll start correctly the next time the 
system boots.  Under the old init system, that wasn't true.
