I installed Solaris 10 on an Intel x86 machine at home. I chose default partitioning, and it allocated a 100 MB or so for the /var partition. Now if I try to do anything, such as install the security patches it complains about disk space. Weird default partitioning scheme.
Not to mention the number of default services that are running on the machine. And they have a new services system. To view the services running on the system you can do:
svcs -a
To turn a service of, you can do:
svcadm disable servicename
To patch solaris 10:
smpatch update
