Description of problem:

glibc rpm (either glibc-2.26-24.fc27.i686.rpm or glibc-2.26-24.fc27.x86_64.rpm) installs ldconfig and sln programs to /sbin/ directory. In Fedora 27, /sbin is not a real directory but a symbolic link to usr/sbin directory. It has tricky and confusing consequence: 

$ which ldconfig 
/usr/sbin/ldconfig

$ rpm -qf /usr/sbin/ldconfig
glibc-2.26-21.fc27.x86_64

$ rpm -q --whatprovides /usr/sbin/ldconfig
glibc-2.26-21.fc27.x86_64

Everything looks ok up to now, BUT:

$ dnf provides /usr/sbin/ldconfig

Error: No Matches found

So, a package requiring /usr/sbin/ldconfig could not be installed with dnf.


Version-Release number of selected component (if applicable):

Fedora 27, glibc-2.26-24.fc27.x86_64.rpm.


How reproducible:

Always


Steps to Reproduce:
1. Install Fedora 27
2. $ dnf provides /usr/sbin/ldconfig


Actual results:

Error: No Matches found


Expected results:

Repo        : @System
Matched from:
Filename    : /usr/sbin/ldconfig


Additional info:

It could be treated as a bug in dnf. But I think since /bin, /sbin, /lib, and /lib64 directories are officially "retired" in Fedora 27, no files should be installed into these directories, all the files should be installed into /usr/bin, /usr/sbin, /usr/lib and /usr/lib64 directories.
