I cannot see any impact except the status of node won't be update when setting 'site.nodestatus=n', you can try to leverage it to solve your issue.
But I am thinking maybe your issue caused by the running of 'getpostscripts' when booting the diskless nodes. You can try to set the site.precreatemypostscripts=1 to improve the performance of getmypostscript operation. I suggest you to try them one by one and then both to see the result.

The process on the service node that is at fault is the "install monitor". This seems to be tied to the site.nodestatus option. Other than disabling this option (and fixing the diskfull reinstall loop bug with it that I reported earlier), is there a way of improving the responsiveness of a service node when it's updating the node's status? Would we lose anything from disabling this option besides the "status" column not being updated?
