Can someone clear something up for me?
[[[

Doesn't the above mean that an apache user (eg, user-supplied CGI
process, PHP script, etc) has the ability to read (and write!) anything
in the filesystem?
Similarly: mailnull, majordomo, bin, etc, appear to get "elevated"
privileges via this file and mac_bsdextended.

Cyrus is a "black box" mail server: the cyrus user normally winds up
owning anything that the IMAP server needs to touch.

# For the nobody account:
${CMD} add subject uid 65534 object not uid 65534 mode rxws;
${CMD} add subject gid 65534 object not gid 65534 mode rxws;
]]]
... and doesn't this (almost, no "a" flag) completely negate the point
of the nobody account in the first instance?
Not quite getting it,
