To implement some Fedora 25 changes (split NSS (Name Service Switch)
subpackages, libcrypt without NSS (Mozilla Network Security Services)
library depdencies), I added additional subpackages to the glibc
packages, namely:
- libcrypt
- libcrypt-nss
- nss_db
- nss_hesiod
- nss_nis
The expectation is that libgcrypt-nss is installed by default, and
system administrators may opt to install libcrypt (with the internal
algorithm implementations instead). libcrypt and libcrypt-nss both
provide the soname-based RPM dependencies required by applications which
need password hashing.
In contrast, nss_db, nss_hesiod, nss_nis are expected to be installed by
system administrators who need the specific functionality. They are not
installed by default. (nss_files and nss_dns remain part of the main
glibc package because their use is pretty much required by all
installations.)
The background for these changes is twofold: We want to reduce minimal
image size (also the gains a very small), and we want to pave the road
towards alternative implementations (based on OpenSSL for libcrypt, and
based on libtirpc for nss_nis).
Thanks,
Florian
