[slurm-users] slurm reboot node with spank plugin

[Tueur Volvo]

I would like to update the linux kernel then reboot the machine and run the
job

for example I would like this:

srun --chooskernel=4.1 hostname

I would like to install kernel 4.1 on my machine, then reboot the machine
and run hostname

if i use srun --reboot hostname, how to tell him to update the kernel
before rebooting ?
if I understand what you mean, I have to use a job-submit plugin ?

like this :

?
