Sticky Bit on Directories
=========================
files inside the directory may be renamed or removed only by the owner of the file, the owner of the directory,
or the superuser (even if the modes of the directory would otherwise allow such an operation). (HP-UX)
Sticky Bit on Executable Files
==============================
the file does not leave swap space once it terminates upon its next execution. when it is executed again by any
user, it is read from the swap space, thus speeding up its execution. (HP-UX)
Sticky Bit on Non-Executable Files
==================================
Sticky Bit on Remote Executable Files
=====================================
tells the system to page the text to the local disk. Otherwise, it is "retrieved" across the network. Of course,
this would only apply when there is actual paging occurring. (HP-UX)
Sticky Bit on Symbolic Links
============================
A symbolic link sticky bit set'd is called a transition link (i.e. links to ease the transition to the new
SVR4 filesystem layout). Transition links are a bit faster, because the linked-to filename is stored in the
inode itself, instead of using an allocation unit to store the link. In order to set the sticky bit on a symlink,
one must use the undocumented lchmod system call (i.e. lchmod("/bin", 041777)).
SUID bit on Direcotries
=======================

SUID bit on Executable Files
============================
execute with the permissions of the owner of the file.

SGID bit on Direcotries
=======================
new files and direcotries created within will be owned by the group who owns the directory
