SU behavior in 11.31

[Eric Yruegas]

Before opening a case with HP support, thought I'd ask the collective if they've noticed, or can explain, the following behavior:

On HPUX 11.11 and 11.23, I using "su" to change users preserves the umask setting. Note I am *not* using the "su -" option, on purpose.

# umask
022
# su {anyotheruser}
$ umask
022

On HPUX 11.31 - it's working differently.

# umask
022
# su {anyotheruser}
$ umask
077

!?!??!? It seems the behavior of SU has changed in 11.31, but I cannot find a bit of documentation on this. Heck, maybe it's a bug?

/etc/profile is consistent across all machines, as well as root's .profile, and the {anyotheruser}'s .profile.

I'm hoping you all are seeing the same behavior on your 11.31 machines.

Thanks!

Hello,

If you are certain that no profiles are
involved, then maybe this helps.
