And if you look further, at updatedb, you'll see this:
# FIXME figure out how to sort null-terminated strings, and use -print0.
if test -n "$SEARCHPATHS"; then
if [ "$LOCALUSER" != "" ]; then
su $LOCALUSER -c \
"$find $SEARCHPATHS \
} | sort -f | $frcode > $LOCATE_DB.n
So, while find may be run as nobody, sort and frcode definitely are not.
And as the comment says there may be something else lurking there.
I vote for coding this in perl.
