Cool, thanks for testing Sam. Apologies for the missing ${SW_IMG}.
And thanks for the 'unshare -U true' suggestion. I gather your point is
that 'unshare -U' will fail in any chroot environment. I'm not an expert
on namespaces but, from what I can tell, that does seem to be true in
all modern kernels as you say. However, 'unshare -U' can fail for other
reasons too - say, if the admin set /proc/sys/user/max_user_namespaces
to 0, or when running a kernel with CONFIG_USER_NS=n. If we assume all
failures mean we are in a chroot, then we risk not configuring kdump in
such environments.
