From: WXbet <[email protected]>
On the target, the postinst of kernel-image-<type> creates the
${KERNEL_IMAGEDEST}/<type> link with a path relative to the current
directory, and the postrm removes it the same way. opkg runs package
scripts in the directory of its caller, so an upgrade started from any
directory other than / makes ln fail. The fallback then copies the image
with install, which the busybox defconfig does not enable:
sh: install: command not found
and the postrm leaves the link behind.
Anchor the link location at / as the rootfs-time case anchors it at $D.
The link target stays relative to ${KERNEL_IMAGEDEST}.

Notes:
The relative path seems to date back to bb946b8cdb ("classes/kernel: Use
a copy of image for kernel*.rpm if fs doesn't support symlinks"), which
moved the link from do_install into the postinst. When $D is set at rootfs
time, the link is still anchored at $D. If the on-target case is meant to
be relative to the current directory, please let me know how package
managers are expected to call it.
