Well given all the other security risks inherent in running in a
dynamically loaded environment, especially with loadable kernel modules,
the additional risks inhernent in dynamically loading your
authentication code are not that much higher.
Personally I'd always pick statically linked environments every time
for security sensitive situations even if it wastes a bit more disk and
It's also important to note that PAM offers almost no useful
functionality when you already have source for everything.....
