pca runs fine in single user mode, and if you can afford the downtime, 
installing patches like that is the safest method anyway.

It might be best to pre-download patches to a directory in the root-partition 
while still in multi-user mode, like:

   mkdir /patches
   cd /patches
   pca --download

So it doesn't depend on a network connection - although I think that in recent 
versions of Solaris the network is up by default in single user mode, too.
