POSIX Access Control Lists

====================================
The statements about Linux systems are no longer always true:
* On some Linux systems, ACL support must be added manually,
although some current distributions now include it by default.
* Not all filesystem types require the acl mount option.

========
The statements about how Linux group ACEs are applied are
not correct. Linux interprets ACLs in the same way that Solaris
and Tru64 do. Thus, the final sentence of the second bullet and
the two following paragraphs (including the example) should
be disregarded.

Missing footnote

CONFIRMED ERRATA FROM AUTHOR

The missing footnote reference mark goes at the end of the first paragraph on that
page (continued from the previous page).

Footnote text:

For simplicity, we are neglecting the overlap in the incremental backup set that
occurs on successive days. For example, on the third day, 30% is the right figure
only if the files that changed are completely distinct from the ones that changed on
the second day. If we assume the change rate is uniform across all files, the actual
change is 30% - (15%*15%) = 27.75%. Ignoring this effect makes the figure's block
size and the table's numbers come out much prettier.
