Re: nilfs_cleanerd not running

[mikael-m2T68/X/qvZAfugRpC6u6w@public.gmane.org]

Hi again,

I am now able to run nilfs_cleanerd after running it as root... :) When 
I am running it with sudo I get below, although I set LD_LIBRARY_PATH 
first:

nilfs_cleanerd: error while loading shared libraries: libnilfs.so.0: 
cannot open shared object file: No such file or directory

Maybe sudo starts a new shell and loses the LD_LIBRARY_PATH variable?

I think it is rather strange and confusing that nilfs_cleanerd says 
'NILFS_CLEANERD_PID=25215' without being able to start a process 
properly. Is that perhaps a bug?

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?

Kind regards,

Mikael Andersson
