fn resolve_host(host: &[u8]) -> Vec<u8> ⓘExpand description
The real host path behind a binding or the root, symlinks resolved.
A binding names a host object, not a symlink to it: /etc/resolv.conf
pointing into /run/systemd/resolve/ must bind the resolver file itself,
or the guest would follow the link inside its own rootfs and find nothing.
Same as PRoot’s realpath on every binding. A relative path becomes
absolute the same way. A path that does not exist (yet) is kept as given.
