Bug 2055953

Description of problem:

The latest version of the Linux Standard Base Core Specification (e.g. https://refspecs.linuxfoundation.org/LSB_5.0.0/LSB-Core-AMD64/LSB-Core-AMD64/libcrypt.html) says that libcrypt.so.1 is part of the Core Specification.

As part of glibc deprecating libcrypt and Fedora (and possibly sibling distros) transitioning to libxcrypt, libcrypt.so.1 seemed to have been dropped by the  Fedora base install. In order to get libcrypt.so.1 and be in stronger compliance with the LSB Core Specification, you need to install the libxcrypt-compat package.


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


How reproducible: Always. Part of base OS install and official container images.


Steps to Reproduce:
1. Install Fedora 35

Actual results:

No libcrypt.so.1 in base install.

Expected results:

libcrypt.so.1 should be in base install and provide the interfaces defined by the LSB Core Specification.

Additional info:

https://refspecs.linuxfoundation.org/LSB_5.0.0/LSB-Core-AMD64/LSB-Core-AMD64/baselib.html says "shall support base libraries." "shall" is not "must" so there is some wiggle room to not contain libcrypt.so.1 by default. However, I believe Fedora is currently an outlier, as other popular distros seem to be providing libcrypt.so.1 and in better compliance with the LSB Core Specification.

Also, `dnf install redhat-lsb-core` does not install libxcrypt-compat. That's potentially another oversight.

https://github.com/indygreg/python-build-standalone/issues/113 describes a real world implication to Fedora not providing libcrypt.so.1 out-of-the-box.
