The issues can never be ironed out, and they don't have to be. You can telnet to your system as myverylonghostname and your DNS or hosts files will resolve the name across the network. Internally, you should set both HOSTNAME and NODENAME in the /etc/rc.config.d/netconf.
NOTE: there is almost no documentation for NODENAME and HOSTNAME except the start/stop script called /sbin/init.d/hostname. Here is a good explanation:

Also oracle 11G ASM requires a short hostname. We found out it is an undocumented bug "feature" and thus the hostname was shortened to 8 characters.

That seems like a really odd length. I wonder why they couldn't make it at least 64 bytes?
A concern we continue to have is that we can only use the shortest supported node/host name length of any software on the server.

Support has not really improved.
I believe long host names is built into 11.31 HP-UX but I've never seen the kinks worked out to my satisfaction either as an add in or built in.
It is still safer to stick with 8 character host names.
As far as SG goes, I've never seen the issue, but there are other things that pop up. Its IMO not worth the hassle.
