Well, I thought you can't install directly to btrfs because of a dependency on zlib needed for compression. Regardless, the installer needs to have the option to mount / or any other directory with options, so for example, btrfs can be mounted with compress and ssd from the get go, making the total installation smaller, which is one big point for using btrfs for me anyway.
The way I did it using a previous alpha was to slow the installer using while 1 in bash, waiting until it mounts /target and /target/boot, then sending SIGSTOP to the installer. Then I unmounted /target/boot, then /target and remounted /target using "mount -t btrfs -o compress, ssd /device /mountpoint" and /target/boot using "mount -t ext4 /device /mountpoint". I then restarted the installer and it went on it's way installing, slowly of course because of the btrfs I/O slowdown bug. Afterwards I modified /etc/fstab to mount / using '-o compress, ssd'.
Unless I am completely blind I see no way to choose mount options using the alternative installer.
The btrfs I/O slowdown bug needs to be backported this kernel if btrfs is going to have any use at all, as it takes way too long to update installations.

I found btrfs by coincidence in Ubiquity at the end of last month and since then I am running Ubuntu on a compressed btrfs on my sub-notebook. Hopefully they will add the compress option officially soon.

Hilarity on skates. But surely it will be worked out somehow.

Trying Out The New Ubuntu 10.10 Installer
Phoronix: Trying Out The New Ubuntu 10.10 Installer
Following last week's Ubuntu 10.10 Alpha 3 release but landing before the Ubuntu 10.10 "Maverick Meerkat" feature freeze this week were a number of last-minute features like X Server 1.9 integration and other updated packages along with the committing of the revamped Ubuntu desktop installer to Maverick. Via this revamped Ubuntu installer it's possible to install proprietary bits directly like support for MP3 audio files and proprietary graphics drivers...
