From: Andrei Gherzan <andrei.gher...@huawei.com> The libnss configuration file is only installed when glibc is used. The inexistence of it on a musl-based rootfs, will make shadow complain about it:
Failed opening /etc/nsswitch.conf This is because shadow will try to use nsswich when dealing with subordinate IDs and the message is just a warning as the tool will still generate them correctly in subuid/subgid files. We drop this log message for class native to avoid an error when rootfs logs are checked ('Failed' will match the regex bitbake is using to check for rootfs generation errors).
