 Description: transitional package for Linux Standard Base init script functionality
  This is an empty package; it's needed only because of Provides: not being
  supported in debootstrap.  It can be safely removed.

 Since version 9.20150826, this package stopped providing the compatibility
-LSB packages and only provides two otherwise important packages:
+LSB packages and only provided lsb-base and lsb-release.
 
-* The "lsb-base" package includes a number of functions used by init.d
-  scripts in some LSB packages.
+By late 2022 (before Bookworm), lsb-base has been subsumed into
+sysvinit-utils while lsb-release has its remaining functionality
+reimplemented without the old complexity.
 
-  For documentation of those functions (and those added for Debian's use),
-  please see the README.Debian file in that package.
+The lsb-base package is gone save for this empty stub, needed only
+because of installer quirks.  It can be purged from your system.
 
-* The "lsb-release" package includes the lsb_release command, which provides
-  information about the installed LSB modules and the underlying distribution.

+lsb-base dependency
+-------------------
+
+In the past, packages including an init script were required to Depend
+on lsb-base.  This is not needed anymore as the included files have been
+a part of the Essential set for a while.  Thus, you can clean it away
+-- but despite lintian being a bit dramatic, there is no rush in doing
+so as Provides: make that dependency harmless.
