Just because libata does not support them doesn't mean you won't see
partitions beyond #15. It has been proposed that libata's next rewrite will
exclude the arbitrary SCSI limit. In the meantime, kpartx and device mapper
can be used to access them if you can figure out how they work. AFAIK, there
are no installers that include this facility.
The disk themselves support unlimited
numbers of partitions, but the operating system doesn't. Currently, Linux
is more limited in this respect that Windows: you are limited to a total
15 partitions per disk, of which 1..4 are primaries, and 5..15 are
logical. Number 0 is the entire disk (that's where 2^4 comes into).
I was thinking in terms of the hardware and partition tables, not
Linux device mappings. I stand corrected in that you can only have 15
numbered partitions 1 - 15.
The number usable for filesystems through libata is actually 14. One of 1-4
has to be an extended for any logicals to exist.
More than 15 can certainly exist; they just can't be accessed directly via
libata.
And as you mentioned, LVM is not portable.
No small limitation for multibooters.
