  To: buildroot

A daemon which handles passwd, group and host lookups for running
programs and caches the results for the next query. This package is
intended to replace glibc nscd. Presently, glibc nscd is not installed
by Buildroot.

unscd depends on glibc because it relies on glibc function
__nss_disable_nscd.

nscd.conf is taken from glibc with unused configurations removed.

+	  Micro Name Service Caching Daemon
+
+	  A daemon which handles passwd, group and host lookups for
+	  running programs and caches the results for the next query.
+	  You only need this package if you are using slow Name Services
+	  like LDAP, NIS or NIS+.
+
+	  This particular NSCD is a complete rewrite of the GNU glibc
+	  nscd which is a single threaded server process which offloads
+	  all NSS lookups to worker children; cache hits are handled by
+	  the parent, and only cache misses start worker children,
+	  making the parent immune to resource leaks, hangs, and crashes
+	  in NSS libraries.
+
+	  It should mostly be a drop-in replacement for existing
+	  installs using nscd.
