    bool "getent"

    help

      This package installs the 'getent' utility, which allows to

      get entries from Name Service Switch libraries. For glibc

      toolchains, it's the real getent program from the C library

      that gets installed, which is NSS-capable. For uclibc and

      musl toolchains, it's a simple wrapper script that emulates

      getent's behavior, since there is no NSS support in uclibc

      and musl.
