Summary: NIS can prevent system bringup

On my build 132 SPARC machine, when the NIS server is down systme bring-up is
hung unless I do an 'svcadm disable nis/client'. Upon boot a 'svcs -xv
svc:/network/service:default' shows:
root at indiana-build-sp:~# svcs -xv svc:/network/service:default
svc:/network/service:default (layered network services)
State: offline since Sun Mar 07 17:26:32 2010
Reason: Start method is running.
See: http://sun.com/msg/SMF-8000-C4
See: man -M /usr/share/man -s 1M ifconfig
See: /var/svc/log/network-service:default.log
Impact: 27 dependent services are not running:
svc:/network/dns/client:default
svc:/milestone/name-services:default
svc:/milestone/multi-user:default
svc:/system/boot-config:default
svc:/system/intrd:default
svc:/milestone/multi-user-server:default
svc:/system/zones:default
svc:/application/graphical-login/gdm:default
svc:/system/filesystem/autofs:default
svc:/system/system-log:default
svc:/network/smtp:sendmail
svc:/system/fpsd:default
svc:/network/dns/multicast:default
svc:/system/avahi-bridge-dsd:default
svc:/network/sendmail-client:default
svc:/system/dumpadm:default
svc:/system/fmd:default
svc:/network/ssh:default
svc:/application/pkg/update:default
svc:/network/http:apache22
svc:/application/pkg/server:default
svc:/network/inetd:default
svc:/system/cron:default
svc:/network/nfs/mapid:default
svc:/network/nfs/server:default
svc:/system/filesystem/reparse:default
svc:/application/opengl/ogl-select:default
While, nearly all of these services can operate without NIS as my nsswitch.conf
is:
passwd: files nis
group: files nis
# consult /etc "files" only if nis is down.
#hosts: nis [NOTFOUND=return] files
hosts: mdns dns nis files
# Note that IPv4 addresses are searched for in all of the ipnodes databases
# before searching the hosts databases.
ipnodes: mdns nis dns files
networks: nis [NOTFOUND=return] files
protocols: nis [NOTFOUND=return] files
rpc: nis [NOTFOUND=return] files
ethers: nis [NOTFOUND=return] files
netmasks: nis [NOTFOUND=return] files
bootparams: nis [NOTFOUND=return] files
publickey: nis [NOTFOUND=return] files
netgroup: nis
automount: files nis
aliases: files nis
# for efficient getservbyname() avoid nis
services: files nis
printers: user files nis
auth_attr: files nis
prof_attr: files nis
project: files nis
To enable SSH and Apache for example, I have to 'svcadm disable nis/client' and
then allow the dependent services to come up so that a 'svcs -xv
svc:/network/service:default' shows all dependencies started:
root at indiana-build-sp:~# svcs -xv svc:/network/service:default
svc:/network/service:default (layered network services)
State: online since Sun Mar 07 17:42:11 2010
See: man -M /usr/share/man -s 1M ifconfig
See: /var/svc/log/network-service:default.log
Impact: None.
And then in anticipation of my NIS server coming back I have to re-enable NIS
with: 'svcadm enable nis/client'. This is a very brittle configuration for
system boot.
