Diskless workstation and some minor issues

[BERTRAND Joël]

	Hello,

	I have installed a diskless workstation (10.2-RELEASE-p14) that mounts 
its rootfs from a NetBSD nfs server. My fstab is :

root at pythagore:~ # cat /etc/fstab
# Device        Mountpoint      FStype  Options Dump    Pass#
192.168.10.128:/srv/pythagore   /       nfs     nfsv3,tcp,soft,intr,rw 
0      0
...
192.168.10.128:/home            /home   nfs     nfsv3,tcp,soft,intr,rw 
0      0
root at pythagore:~ #

	First question. I have installed this diskless workstation with an USB 
stick. Now, FreeBSD kernel mounts rootfs over NFS. But in a first time, 
it tries to mount usbus0 (!) :

Apr  9 10:48:00 pythagore kernel: Root mount waiting for: usbus2 usbus1

Apr  9 10:48:02 pythagore kernel: NFS ROOT: 192.168.10.128:/srv/pythagore

	I don't understand why kernel tries to mount an USB rootfs... And I 
haven't found how fix this trouble.

	Second trouble. /var/log/message contains a lot of :
Apr  9 10:50:00 pythagore atrun[862]: cannot lock /var/at/jobs/: 
Permission denied

	Of course, lockd and statd are running on nfs server. Permission on 
/var/at are :

root at pythagore:/var/at # ls -al
total 8
drwxr-xr-x   4 root    wheel  512 Aug 12  2015 .
drwxr-xr-x  28 root    wheel  512 Apr 15 09:14 ..
drwxr-xr-x   2 daemon  wheel  512 Aug 12  2015 jobs
drwxr-xr-x   2 daemon  wheel  512 Aug 12  2015 spool
root at pythagore:/var/at #

	I don't understand where is the mistake.

	An third trouble, this workstation runs cupsd. When I send a job to 
printer, cupsd run as expected but aborts after job is completed. In 
/var/log/cups/error_log, I have :

E [19/Apr/2016:12:44:34 +0200] Unable to create 
"/usr/local/etc/cups/printers.conf.N": Operation not permitted
E [19/Apr/2016:12:45:12 +0200] Unable to create 
"/var/cache/cups/job.cache.N": Operation not permitted
E [19/Apr/2016:12:45:12 +0200] Unable to create 
"/var/spool/cups/c00032.N": Operation not permitted

	I have checked permissions on directories (and config file) without any 
result, but I have seen that permissions on /var/spool/cups are 
overwrittem by cups (to drwx--x---).

	All help will be welcome. Thanks in advance,

	JB
