warning: config, failed to purge temporary directory
I am getting the warning
warning: config, failed to purge temporary directory...
every time I use knotd or knotc.
I think it is related to the fact that I am running on a Raspberry Pi 4 with the entire disk on NFS mounted with the following options
(rw,relatime,vers=3,rsize=4096,wsize=4096,namlen=255,hard,nolock,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=10.74.8.190,mountvers=3,mountproto=tcp,local_lock=all,addr=10.74.8.190)

I am guessing that something is not closing a file??
