Bug#1060233: libc6: Missing libdl.so

[Paul Szabo <paul.szabo@sydney.edu.au>]

Dear Aurelien,

At bullseye, I explicitly needed to use libdl e.g. with constructs like

  export LD_LIBRARY_PATH=/somewhere
  export LD_PRELOAD='libdl.so gconf_client_get_string.so'

with code using dlopen() to then replace (modify?) library calls.
You suggest that there is no longer a need to explicitly preload libdl:
great, will simplify all my instances. (Until then, the useless symlink
allows the scripts to work as before.)

Also: why provide the "empty" libdl.so.2 object, still?

Thanks, Paul
