None that I can find relating to reiserfs

/dev/root / reiserfs rw,noatime 0 0

I have attached the full output but the following lines stick out to me.

access("config.log", W_OK)              = 0
unlink("config.log")                    = -1 EACCES (Permission denied)
write(2, "rm: ", 4rm: )                     = 4
write(2, "cannot remove `config.log\'", 26cannot remove `config.log') = 26
write(2, ": Permission denied", 19: Permission denied)     = 19
