A similar problem is logged in "iptun" service as well:

# grep 'not found' /etc/svc/volatile/*log
/etc/svc/volatile/network-iptun:default.log:/lib/svc/method/net-iptun: 
line 81: /usr/bin/cut: not found
/etc/svc/volatile/network-physical:default.log:/lib/svc/method/net-physical: 
line 722: /usr/bin/nawk: not found
/etc/svc/volatile/network-physical:default.log:/lib/svc/method/net-physical[733]: 
/usr/bin/sort: not found [No such file or directory]
/etc/svc/volatile/network-physical:default.log:/lib/svc/method/net-physical: 
line 733: cat: not found
/etc/svc/volatile/network-physical:default.log:/lib/svc/method/net-physical[733]: 
/usr/bin/nawk: not found [No such file or directory]
/etc/svc/volatile/network-physical:default.log:/lib/svc/method/net-physical[317]: 
/usr/bin/cut: not found [No such file or directory]
...

But it does at least depend on "physical" and if that would be fixed
by revised dependencies (to run when /usr is properly present) - so
should be "iptun".
