Oh indeed, I can reproduce it.

The problem is that lshd resets the umask when it starts (in
src/daemon.c:daemon_init) but never changes it again.

Perhaps we should be using pam_umask and login.defs (although I’m unsure
if lshd would honor it), or alternately add explicitly set the umask in
/etc/profile.

Thoughts?

Thanks,
Ludo’.
