[OpenIndiana-discuss] What is the status of UEFI boot support?

[zeitraffer]

Hello!
The current documentation does not claim that current OI supports UEFI, but
I see that the current live disk can boot in UEFI.
I have tried to boot it into UEFI and to make install by the text installer
onto the GPT drive.
After installation I have seen 3 partitions, but the boot one is not of FAT
type, so UEFI cannot boot from it.
What am I doing wrong? Does OI support UEFI currently?
