One thing I've noticed over several version of sunos and solaris is that /opt
tends to be more where the officially supported but non-core OS packages get put
(ever noticed on Solaris 7 the existence of /opt/ENSsudo ?) - I include things
like Veritas volume manager, SIMS (Sun's imap/pop server) etc, and incidentally
HP JetAdmin likes to go in /opt also. As for improvement in packaging systems,
well, SYSV-pkg is certainly a long way from tar (remember old slackware?) but
there are bits about it that I don't like. It is, however, a commercial-unix
standard so we are kinda stuck with it for at least a while.

solaris leaves /usr/local alone (although Solaris 8's bonus pack of OSS stuff
does get installed under there somewhere), which is a good thing. /usr/local and
/export/home are really the only two subdirs which the installation system will
not scream too much about leaving alone.

clustering...<shudder> - I've yet to see a really nice solution to this from any
vendor, Solstice DiskSuite (now builtin to Solaris 8 instead of being a
server-only package)..... play with it.
