ssh setuid und $HOSTALIASES

Hallo,

Ist es ein Feature oder ein Bug, dass /usr/bin/ssh die
HOSTALIASES Variable ignoriert, wenn es mode 4755 hat?

danielt(at)uliae:~> cat $HOSTALIASES
obi oberon.pilgerer.org
danielt(at)uliae:~> ls -l /usr/bin/ssh
-rwsr-xr-x 2 root wheel 202460 May 3 15:14 /usr/bin/ssh*
danielt(at)uliae:~> ssh obi
ssh: obi: No address associated with hostname
zsh: exit 255 ssh obi
danielt(at)uliae:~> SU chmod 0755 /usr/bin/ssh
danielt(at)uliae:~> ls -l /usr/bin/ssh
-rwxr-xr-x 2 root wheel 202460 May 3 15:14 /usr/bin/ssh*
danielt(at)uliae:~> ssh obi
danielt(at)oberon.pilgerer.org's password: ^C
danielt(at)uliae:~> SU chmod 4755 /usr/sbin/ssh
chmod: /usr/sbin/ssh: No such file or directory
zsh: exit 1 sudo chmod 4755 /usr/sbin/ssh
danielt(at)uliae:~> SU chmod 4755 /usr/bin/ssh
# Das ist wieder seltsam
danielt(at)uliae:~> ls -l /usr/bin/ssh
-rwsr-xr-x 2 root wheel 202460 May 3 15:14 /usr/bin/ssh*
