Hi.
I have seen this lines in the current glibc release notes
https://sourceware.org/glibc/wiki/Release/2.38
```
2.1. Building libcrypt is disabled by default
If you still need Glibc libcrypt, pass --enable-crypt to the configure
script.
Note that libcrypt may be removed completely in future Glibc releases.
Distributions are encouraged to provide libcrypt via libxcrypt[1],
instead of relying on Glibc libcrypt.
```
The libxcrypt page mention to be backward compatible but we should keep
an eye on this, IMHO.
Regards
Alex
