Yes, it's UFS2, so probably that was a reason.
rootnoverify (hd0,1) fails:

Error 13: Invalid or unsupported executable format

Fortunately,

rootnoverify (hd0,2)
chainloader +1

finally works ! Slices are:

swap     1 GB    ad0s3b
/home1   1 GB    ad0s3d
/       28 GB    ad0s3a

Why 2, not 1 ? I'm a little bit confused.

Anyway, thanks a lot for your help.
