        Hello,

        
        the “-p /sbin/ldconfig” syntax triggers a special behavior
          in RPM if the scriptlet is otherwise empty.  In your
          case, the “%post libs” scriptlet also actually, surprising as
          it may seem, includes the following lines:

        
          ##-----------------------------------------------------------------------------

            ## All %files should be placed here and
              keep them sorted

          
          ##

          
        and hence is not empty.  So RPM skips the special behavior,
          and executes /sbin/ldconfig
          with the usual additional value of $1
          as described in https://fedoraproject.org/wiki/Packaging:ScriptletSnippets?rd=Packaging/ScriptletSnippets
          .

        
    Mirek,

    
    Thanks for your quick reply. I think it should be intelligent enough
    to ignore comments as comments are supported in spec file. Looks
    like a bug to me.

    
        What you have done is a correct workaround, though by
          bypassing the special treatment of /sbin/ldconfig
          the package installation will be somewhat less efficient
          because /sbin/ldconfig will be executed more times than
          necessary.  Another, more efficient, but more difficult to
          maintain, alternative is to avoid comments within the
          scriptlet sections by somehow reordering the spec file.

        Hi All,

          
          Recently we came across a issue i.e. bz [1] , where ldconfig
          returned error as below on Fedora 20 machine (same issue is
          present in other Fedora variants too).

          
          "yum remove glusterfs-libs" giving some Non-fatal POSTUN scriptlet failure.

/sbin/ldconfig: relative path `0' used to build cache
warning: %postun(glusterfs-libs-3.6.0-0.1.beta1.fc20.x86_64) scriptlet failed, exit status 1
Non-fatal POSTUN scriptlet failure in rpm package glusterfs-libs-3.6.0-0.1.beta1.fc20.x86_64


          The fix to this issue is replacing "%post libs -p /sbin/ldconfig"
          in to two lines [3]. But according to Fedora
          documentation [2] "%post
              libs -p
            /sbin/ldconfig" is the right
            way to do it. Which is not working for us. Seems like it is
            changed now but the documentation is not updated. 

          
          Thoughts?
