[pbs-devel] [PATCH v4 proxmox-backup 5/5] docs: mention different name resolution for statically linked binary

[Christian Ebner]

Add a note mentioning that the statically linked binary does not use
the same mechanism for name resolution as the regular client, in
particular that this does not support NSS.

The statically linked binary cannot use the `getaddrinfo` based name
resolution because of possible ABI incompatibility. It therefore is
conditionally compiled and linked using the name resolution provided
by hickory-resolver, part of hickory-dns [0].

 ================================ ================== ================== ===========
 
+.. Note:: If you are using the statically linked binary of proxmox backup client
+   name resolution will not be performed via the mechanisms provided by libc,
+   but uses a resolver written purely in the Rust programming language.
+   Therefore, features and modules provided by Name Service Switch cannot be
+   used.
