Not really sure what to do about this:
$ grep nobody /etc/passwd
nobody:*:-2:-2:Unprivileged User:/dev/null:/dev/null
$ uname -a
Darwin windhund.schwern.org 6.4 Darwin Kernel Version 6.4: Wed Jan 29 18:50:42 PST 2003; root:xnu/xnu-344.26.obj~1/RELEASE_PPC Power Macintosh powerpc
$ perl -wle 'print scalar getpwnam("nobody")'

passwd in /usr/include/pwd.h looks normal:
struct passwd {
char *pw_name; /* user name */
char *pw_passwd; /* encrypted password */
uid_t pw_uid; /* user uid */
gid_t pw_gid; /* user gid */
time_t pw_change; /* password change time */
char *pw_class; /* user access class */
char *pw_gecos; /* Honeywell login info */
char *pw_dir; /* home directory */
char *pw_shell; /* default shell */
time_t pw_expire; /* account expiration */
};
and uid_t is defined in sys/types.h as:
typedef u_int32_t uid_t; /* user id */
and u_int32_t is in ppc/types.h as an unsigned int as you'd expect:
typedef unsigned int u_int32_t;
As far as I can tell its perfectly normal for nobody to be set to
-2 on OS X, at least in Apple's universe.
I noticed this because it meant perldoc couldn't drop privledges. It kept
trying to setuid to 2**32-2.

If I got anything to say, I'll say it with lead.
