Is that perhaps a bug? Seems that libnilfs.so is loaded when its function is used first time. nilfs_cleanerd first tries to deliver PID to the parent process and then call a function of libnilfs. So, this order looks to be natural. > > My problem is still: > > [root@nixos:/home/mikael]# nilfs_cleanerd /dev/mapper/cryptroot > nilfs_cleanerd: error while loading shared libraries: libnilfs.so.0: > cannot open shared object file: No such file or directory > > If I set LD_LIBRARY_PATH, I am however able to start nilfs_cleanerd as > root. > > Any ideas? Try ldd to investigate library dependency. $ ldd /sbin/nilfs_cleanerd If libnilfs.so is "not found", add the library path where libnilfs.so exists, to /etc/ld.so.conf or /etc/ld.so.conf.d/*.conf. And, then run ldconfig. Usually we don't have to care this kind of task. It looks like there is a problem in the NixOS distro package or your system environment.
