Hello,
One year later and I have found some time to work on this.

Woops, sorry for not mentioning you. Well at least it was clear from
the page I referred to. :)

I like it!
I merged your patch into my branch [1] in rev. 37. (I'm also not used
to bzr, but it looks like the merge succeeded.)

You're right, the script should detect all Haiku versions. So I added
the detection of the non package management Haiku builds back.
The partition type provided by grub-probe has changed in the meantime
[2] and the partition can be mounted with befs-fuse [3], so I also
modified the supported partition types.
In case of befs-fuse, a virtual folder named 'myfs' gets added in
which the file system contents are placed. Therefore, 'myfs' needs to
be added to the mount point variable. I intend to try to remove this
'myfs' folder from befs-fuse (tried once in the past [4]), but this
could take a while so for now this 'hack' is needed.
I've attached a git patch against the current git tree, containing all
previous changes. I've tested it with several different Haiku versions
(R1a3, R1a4, x86_64 non-PM, nightly, x86_64 nightly) and found no
problems. I would appreciate additional review and testing, though.
Kind regards,
Jeroen Oortwijn

Subject: [PATCH] Change Haiku detection (package management)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
* Added detection of Haiku package management versions
* Added Haiku version info code by François Revol
* Modified the supported partition types
- When not mounted, the grub-probe utility detects it as 'bfs'.
- When mounted with the befs kernel module, it's get detected
as 'befs'.
- When mounted with befs-fuse, it's get detected as a FUSE
partition.
* Change mount point when partition is mounted with befs-fuse
When the partition is mounted with befs-fuse, it will add a
virtual folder 'myfs' in which the file system contents are
placed. This folder needs to be removed from befs-fuse, but
in the meantime add this folder to the mount point so that
Haiku can be detected.
