Nexenta & Belenix notes OSDevCon
Nexenta: Martin Man
-------------------
Martin's presentation was expert, had many demonstrations and highlighted Unix for humans concept. He talked about the Debian social contract: you can use it free and it will stay free. He mentioned the Debian Free Software Guidelines. He described the Ubuntu Code of Conduct: we value anything you contribute and we respect that you have no time to work on it.
Nexenta, OpenSolaris for humans, packaging and compile changes.
Issues: partitioning and installation
Sun compiler and GNU gcc compiler
linker bugs not being worked

Belenix: Moinak Ghosh
---------------------
Live media changes default to boot RAMdisk (this is main difference in addition to what Joerg discussed). Also, pre-built repository.db to save time at boot. You want this because Live media boot is like a 'first boot' every time. Pre-populate driver_aliases and order block files on CD. Moinak used DTrace to figure this out, to determine the order. Compress 1.8 GB to 700 Mb, then you read one block and get two blocks worth of data, uses HFSF for decompression. Uses I/O scheduler to make blocks consecutive (re-order and coalesce). Then make them adjacent to like blocks, and call them all as one request so that the disk head always seeks in the same direction.

USB boot goes like this:
1. Insert thumb drive
2. Go to BIOS
3. Expand +
4. Switch boot order of HD and thumb drive
This is great because you can have and save state with USB drive. For example, you could add a user account and when you boot on another machine, that new user will exist. You can also have encryption if you lose the drive. It requires only a computer and BIOS support for USB boot.
LiveDVD will be in Caimen.
Comments: We need an online software repository for cooperation between distributions.
