Hello,
You might have seen that we are trying to eliminate /sbin/ldconfig from
scriptlets which would speedup installation / upgrade of packages
**significantly**.
One of cases Florian brought that in case of libcrypt/libcrypt-nss, libraries
didn't have symlinks, so if it would not call ldconfig in its scriptlet, then
any packages which depend on libcrypt.so would fail to execute.
In 99% (this number came just out of my head, not a real investigation) of
packages, we always package those symlinks.
So I'm going to push change to glibc which during build process executes
ldconfig in buildroot which is forcing to create those symlinks and your
package would fail to build with something like:
error: Installed (but unpackaged) file(s) found:
/usr/lib64/libhello.so.1
To disable this you would need to use `%undefine __brp_ldconfig` and you really
need to make sure that you have %post/%postun scriptlets with /sbin/ldconfig.
The plan is to get this in, then get transfiletrigger in glibc which would
execute ldconfig just **once per transaction** and then start removing
scriptlets from packages.
Just FTR: it is one very good reason why those DSO SONAME symlinks *must be packaged*.
If those files will be not packaged simple "rpm -Va" cannot verify those symlinks that they've for example been repointed to some other DSO files with some malware.
In other words: any Fedora package which does not package DSO SONAME symlinks it is broken package, and it is completely independent fact from whole ldconfig discussion.
