As I've said a few times, the terminology can be confusing. It's
extremely context sensitive. Note that I said bootable JFS can not be
installed to a JFS volume. A JFS volume is by definition one or more type
35 partitions. The bootable JFS volume is JFS formatted, but not a JFS
volume.
If you look with dfsee, you will see that the bootable JFS volume is a
type 7 partition, just like a bootable HPFS partition.

It's not really a magic or a trick. It's just code. Any partition type
can be JFS formatted as long as the format program (UJFS.DLL) supports it.
IBM chose not to provide this support. The bootable JFS technology
replaces UJFS.DLL with one that does not have this limitation. There is a
bit more code involved in the process. The other filesystem specific
components in the boot chain need to be replaced with components that work
with JFS formatted partitions. These include the boot sector, the boot
loader (uFSD) and OS2BOOT (the mFSD).
There would be no problem doing a bootable FAT32 or a bootable Reiser if
there was sufficient need or desire to write the code.
There's no technical reason that the bootable JFS volume could not be JFS
partition (i.e. type 35). The uFSD and the mFSD would be more
complicated, but that's all.
