This is difficult, because unless you tell it by yourself, the kernel
has no chance to find out how it is called itself. Imagine you
create a file "/nameofkernel" which contains for instance the line
"/386bsd.testkernel". Who should maintain it if not you yourself?
The secondary bootloader has enough trouble to locate the kernel image
itself on the root device, and cannot create and write files in advance to
this. Even creating a symbolic link from /bootedkernel to
/386bsd.testkernel is too complicated.
A possible solution could be that the running kernel identifies its inode
and creates such a link by itself. But what if it was booted from a
remote readonly partition by bootd?
The best idea would be to leave this as is, for the reason that the
normally used kernel has the name '386bsd'. If you test a new version
with a different name, you may accept the problem with savecore or
rename your /etc/rc to a different one which does not contain savecore.
