multiuser milestone
 

Hi,

I am new to Solaris and while reading, I came across something called "multiuser milestone" in SMF

What actually is "multiuser milestone"??

svc:/milestone/multi-user:default is equivalent to previous Solaris releases run level 2 while multi-user-server is the default one, equivalent to run level 3.
As you aren't familiar with Solaris, what are you familiar with ?
Different OSes have different run levels definitions.

I am from Linux world...we do have /etc/inittab which talks about different run levels in Linux.

I am a bit confused. In Solaris 10, in that case, does it represent multiuser mode ?

What is the difference here between multiuser mode and full multiuser mode ? Is it something like run levels 3 and 4 in linux ?

They aren't equivalent. As far as I know, no linux distribution make a distinction between multi-user (rc2) and multi-user with network services (rc3) like Solaris does while Solaris has no specific run-level for enabling the graphic environment.
