Solaris 11.1 sshd mystery

Hi all,

on two of my x86 systems I have Solaris 11.1 installed and both are on the
same patchlevel:

# pkg info entire | grep FMRI
  FMRI: pkg://solaris/[email protected],5.11-0.175.1.6.0.4.0:20130401T151332Z

Both are using the same version of ssh

# pkg info pkg://solaris/service/network/ssh | egrep FMRI
  FMRI: pkg://solaris/service/network/[email protected],5.11-0.175.1.6.0.3.2:20130322T212817Z

On both systems 'pkg verify' and even 'elfsign verify' does not show any
problems.

But the binaries are not identical. They have diffent size and understandably
different md5 checksums.

{sys1}# digest -a md5 sshd
1edee258edb15bb936b66427ec32f72c

{sys2}# digest -a md5 sshd
8e3a0f52ee3d06cafee7c17b1ccb5b49

{sys1}# ls -l /usr/lib/ssh/sshd
-r-xr-xr-x   1 root     bin        12608 Apr 12 07:36 /usr/lib/ssh/sshd

{sys2}# ls -l /usr/lib/ssh/sshd
-r-xr-xr-x   1 root     bin        12584 Nov 19 10:03 /usr/lib/ssh/sshd



Can this be normal behaviour?


Thanks in advance for any explantion.

Greetings

Willi
