It's been my observation that this won't be fixed.
I've run into the same problem, not to mention I believe Oracle did too.
If you look in /usr/include/sys/param.h you'll find the following:
#define MAXSYMLINKS 20
Just like Sun (and HP). The only difference is that this number is ignored
by the kernel. In fact if you look in the kernel /usr/src/linux/fs/namei.c
you'll find the following comment:
* This limits recursive symlink follows to 8, while
* limiting consecutive symlinks to 40.
- - ---- but if you actually look at the code a few lines later you get
if (current->link_count >= 5)
goto loop;
if (current->total_link_count >= 40)
goto loop;
Bottom line. Any nesting greater than 5 fails.
The fix - recompile the kernel with the 5 replaced by 10.
It used to be claimed that since the name resolution was done with a recursive
algorithm, there was concern about using more kernel stack space. But
I believe the recursive algorithm has been removed. Just the prohibition
for a nesting level greater than 5 remains.
