On Fedora Rawhide mount/umount is linked against libsystemd, which then
breaks the binaries in sanitizer runs, as we try to run instrumented
code from an uninstrumented binary:
bash-5.3# ldd /usr/bin/mount
linux-vdso.so.1 (0x00007fa757ef9000)
libmount.so.1 => /lib64/libmount.so.1 (0x00007fa757e84000)
libselinux.so.1 => /lib64/libselinux.so.1 (0x00007fa757e51000)
libc.so.6 => /lib64/libc.so.6 (0x00007fa757c56000)
libblkid.so.1 => /lib64/libblkid.so.1 (0x00007fa757c16000)
libsystemd.so.0 => /lib64/libsystemd.so.0 (0x00007fa757400000)
libpcre2-8.so.0 => /lib64/libpcre2-8.so.0 (0x00007fa75734f000)
/lib64/ld-linux-x86-64.so.2 (0x00007fa757efb000)
libclang_rt.asan.so => /usr/lib/clang/22/lib/x86_64-redhat-linux-gnu/libclang_rt.asan.so (0x00007fa756800000)
libm.so.6 => /lib64/libm.so.6 (0x00007fa7566e4000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007fa7566b7000)
libstdc++.so.6 => /lib64/libstdc++.so.6 (0x00007fa756400000)
bash-5.3# mount
==458==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.
This then breaks the whole machine, as mount is quite essential during
boot.
Let's just add mount/umount to the list of wrapped binaries to fix this.
