But I still think 6 is too small from user level point of view, as
Petter wrote. The example is /usr/lib library links. I got bug
report which complained that a library want to use "bounce" link:

/usr/lib/liba -> /etc/alternatives/liba -> /usr/lib/another/libb.

If .so file uses major.minor scheme, then /usr/lib/liba.so links:

/usr/lib/liba.so -> /usr/lib/liba.so.2 -> /usr/lib/liba.so.2.3

and so on. It can easily exceed 6 symlinks. I think the correct fix
is to make VFS not to overflow stacks. Is it allowable change?
