Help with dual boot 1.3 / 3.1

[zipper]

I think it just modifies the filesystem - I once went from FFS-DC to FFS without touching the files. But a backup is always recommended.

Hello!
I want to do a similar thing on my A500+ as well.
I never tried, but my idea would be to have a small boot partition with a version control in Startup Sequence and then redirect SYS: (if possible - I know it's the boot partition) to the corresponding partition regarding selected Kickstart (1.2, 1.3, 2.0, 3.1).
In this case no messing with C commands, libraries and so on.
Even if a common partition with SYS1.2, SYS1.3, SYS2.0, SYS3.1 directories would work in theory, remains the common file system problem (there should be PFS/SFS under 1.3 anyway).
Let me know if you have a clue...

Eeek!  How do I do this?  

HdToolBox / Partition Drive / Click on partition / Advanced / etc. etc.?

... then click "Add/Update...". Is there anything listed? If not, click "Add New File System..." and find the disk version of FFS. It's on the 3.1 Install disk in the L directory. It should be v40.1. I think the disk version of FFS was designed with dual-boot systems (read: 1.3 compatibility) in mind. Make sure the identifier is 0x44f5301 - that's non-International mode.

EDIT: I think you should also copy the disk-based FFS to L: on both your system partitions.

Thanks man!  The backing is all done with an old analogue Bontempi organ I found in the garbage and had to revive.

With this

I confirm the theory sys1.3 and sys3.1 on a PFS3 formatted disk.
The early commands (assign, if, ... ) must be 1.3 compatible.

It can be transposable from a boot disk to an autoboot hard disk with RDB and the following PFS3 1.3.

@ Gilloo: thanks for answer.
So I can pass some time experimenting on the multi partition option.
Anyway the idea couldn't be realized without the recently released PFS3 for 1.3 (or everything formatted with FFS).
Thanks!
