It also caused a lot of troubles with zones, as /usr isn't writable in
"sparse root" non-global zones. The problems included at least:
- Inability for non-global zone administrators to choose which
version of Java to make the default; the global zone administrator
chooses, and all others get read-only copies.
- Failures in packaging and patching postinstall scripts (mostly
related to the above Zones issues).
- Surprises for users, such as seeing that installing an old Java
just for compatibility suddenly switched the default (because the
rule is "last to install wins").
I agree that it can probably work, but the way it was done for Java
wasn't without warts.
