Hi John,
as you pointed out, DNS is not available until /usr is mounted -
looking at SMF dependencies, I think it is expected:
$ svcs -d svc:/network/service:default
...
online Sep_17 svc:/system/filesystem/usr:default
...
/lib/svc/method/net-svc start method of svc:/network/service:default
SMF service is the one which populates /etc/resolv.conf:
...
if [ "$_INIT_NET_STRATEGY" = "dhcp" ]; then
dnsservers=`get_dhcp_var DNSserv`
dnsdomain=`get_dhcp_var DNSdmain`
else
dnsservers=""
dnsdomain=""
fi
if [ -n "$dnsservers" ]; then
#
# add settings retrieved from dhcp server to
/etc/resolv.conf
#
update_resolv "$dnsservers" "$dnsdomain"
#
# Add dns to the nsswitch file, if it isn't already there.
#
update_nss hosts
...
Since it calls bunch of binaries from /usr,
it has to wait until /usr is available - from
/var/svc/manifest/network/network-service.xml:
...
<!--
We require the root, usr and minimal filesystems, since
this service writes to/reads from /tmp, /etc, /var and
runs programs under /usr.
-->
<dependency
name='filesystem'
grouping='require_all'
restart_on='none'
type='service'>
<service_fmri value='svc:/system/filesystem/root' />
<service_fmri value='svc:/system/filesystem/usr' />
<service_fmri value='svc:/system/filesystem/minimal' />
</dependency>
...
AI currently uses DNS only for resolving hostname of IPS repository,
everything else is provided in form of IP addresses - installadm(1M)
takes care of the configuration.
NIS/NIS+ is currently not supported by AI, but I am not sure if it
would help, since it seems (after taking a quick look at SMF
dependencies) that it waits for /usr as well.
Thank you,
Jan
