out of the box, umask should default to something more typical.

I can’t reproduce this.  For instance, in the system created with:

  guix system vm gnu/system/examples/bare-bones.tmpl

‘umask’ returns 0022.

Could it be that your user accounts have shell startup files like
~/.bashrc that specify a different umask?

Thanks,
Ludo’.

I don't think so. I have attached a log of dot files for a sample user
(glc4) and the most current (feb 12) system config.

'system-generations-package-list' file was generated by 'emacs' 'M-x
guix-system-generations' '"select" (current) generation'

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’.

Thanks for looking into this. Sorry, but I'm not qualified to comment.

I never pay attention to umask, but set it in /etc/profile seem the right thing to me. IIRC, debian and exherbo set it in there too.
