Again, the only drawback is that we will no longer be able to override a symbol using LD_PRELOAD. Honestly, I never did that. I don't see any use case for that. But I used LD_PRELOAD on the libc multiple times to mock the system clock for example. > > > > If someone really needs LD_PRELOAD, it's quite easy to build a custom Python without -fno-semantic-interposition. > > Mock's Nosync plugin use LD_PRELOAD: > https://github.com/rpm-software-management/mock/wiki/Feature-nosync IIUC mock would not be affected by this change. The LD_PRELOAD limitation described applies to symbols that are in the libpython.so library. Those docs suggest mock is replacing the fsync() API in glibc with its LD_PRELOAD, so that should continue to work as normal.
