At boot time I am getting 18 start jobs all trying to start which causes failures. I want to limit the maximum concurrent start jobs to either 1 or 2. How do I do this.
I have increased all the timers but still get failures in start jobs:- DefaultTimeoutStartSec=300s DefaultTimeoutStopSec=300s DefaultTimeoutAbortSec=300s DefaultRestartSec=15000ms DefaultStartLimitIntervalSec=180s DefaultStartLimitBurst=60s
I also noticed that the hard disk write cache is off & the read ahead is 255, perhaps it possible to change these at boot, to cache on & say 8 for read ahead.
