Re: bug in [ -f file ] test

[root]# cat /usr/lib/sysctl.d/50-default.conf | grep fs
fs.protected_hardlinks = 1
fs.protected_symlinks = 1

I guess this explains it. Problem is (my problem now) that it breaks the startup scripts of a $50000 software, which does work on an older FedoraCore. Is this a kernel problem then?

Thanks to all for your help.
