stat("acout.57vRTc", {st_mode=0404, st_size=0, ...}) = 0
lstat("acout.3Dh0Oi", {st_mode=S_ISUID|0161, st_size=0, ...}) = 0
lstat("acout.57vRTc", {st_mode=0404, st_size=0, ...}) = 0
rename("acout.3Dh0Oi", "acout.57vRTc")  = 0

That is the end of the mv call.  Do strace -o <file> <command>.  Look in file,
you will find every system call the program made.

Now if you are truly curious, you could grab the source for glibc and look at
the rename fuction and see what it does.

The stat() calls check perms and what not.
