Description Tristan Miller 2023-11-01 14:06:28 UTC 
Since version 2.7.0, dar has supported parallel encryption and compression with its -G command-line option, as well as zstd compression using the --compression=zstd command-line option.

However, the version of (lib)dar packaged by openSUSE Tumbleweed has these two features disabled:

$ dar --version

 dar version 2.7.12, Copyright (C) 2002-2023 Denis Corbin
   Long options support         : YES

 Using libdar 6.7.0 built with compilation time options:
   gzip compression (libz)      : YES
   bzip2 compression (libbzip2) : YES
   lzo compression (liblzo2)    : YES
   xz compression (liblzma)     : YES
   zstd compression (libzstd)   : NO
   lz4 compression (liblz4)     : NO
   [...]
   Multiple threads (libthreads): NO 

Have these two features been disabled intentionally?  If not, could the package please be updated so that these two features are enabled?
