[PATCH 2/2] tools/bootconfig: Test listing keys at the maximum depth

[Zhiqi Zhang]

Check that a key with 16 components can be attached to an initrd and
listed in full, and that a key with 17 components is still rejected.
Compare the complete list output instead of relying on the tool's
exit status: a failed key composition currently stops listing without
changing that status.

The existing good sample checks exercise the compact tree renderer,
which does not use xbc_node_compose_key_after() and therefore misses
its depth boundary error.

I wrote and ran these regression tests after reviewing the fix.
