[Bug 1025385] [NEW] Ubuntu installer doesn't offer option for btrfs subvolume

[Theo Markettos]

Public bug reported:

The 'alternate' installer for Precise, even in expert mode, doesn't
allow the selection of a subvolume ID when installing into a btrfs
partition.

I have a btrfs partition that already contains some data.  I wanted to
install Ubuntu into it in a fresh subvolume.  I created the subvolume,
so I now have a subvol called '@precise'.  I go into 'manual disk
partitioning'.  It offers me the option to use a btrfs partition and not
reformat it, but no choice of subvolume ID.  That means it will install
all over the existing files.  The mount option would be subvol=@precise,
but the installer doesn't allow me to add that or select from anything
but a very limited set of mount options.

More generally, perhaps there could be an option in the disk partition
settings to add user-supplied textual mount options?

I eventually installed manually via debootstrap, chroot and much fiddling, via these instructions:
