Title:
  please drop ldconfig wrapper around ldconfig.real if no longer needed

Status in glibc package in Ubuntu:
  Triaged

Bug description:
  In 2012 (eglibc 2.16-0experimental0), the Debian packaging for glibc
  renamed upstream's /sbin/ldconfig static binary to
  /sbin/ldconfig.real, and added a wrapper script around it,
  debian/local/sbin/ldconfig (installed as /sbin/ldconfig) which defers
  regeneration of ld.so.cache to a dpkg trigger if it is not immediately
  needed. This was a workaround for redundant calls to ldconfig by
  packages' maintainer scripts, mainly in code generated automatically
  by debhelper's dh_makeshlibs.

  In 2015 (debhelper 9.20151004), dh_makeshlibs stopped emitting those
  calls to ldconfig: instead, it now relies on glibc's dpkg trigger.

  In 2016 (glibc 2.22-0experimental2), Debian's glibc responded to that
  change by removing the workaround: since then, /sbin/ldconfig *in
  Debian* is upstream's static binary again, and there is no
  ldconfig.real.

  However, Ubuntu's glibc never removed the workaround: /sbin/ldconfig
  in Ubuntu questing is still a script wrapper, which conditionally runs
  /sbin/ldconfig.real, which is the actual static binary built by
  upstream glibc. This is a source of awkwardness for container
  technologies like Valve's Steam Runtime that want to work with the
  upstream ldconfig binary directly.

  It's now been a decade since dh_makeshlibs stopped emitting redundant
  calls to ldconfig. Please could glibc in Ubuntu stop working around
  them?
