[Bug 48734] Re: Home permissions too open

[Giovanni Pelosi]

Probably, behind the original decision there were also issues of home
access, required by some unprivileged services, like apache (userdir).

Today, letting all users accessing any ~/Doc,~/Pic,~/Video look like a
huge security hole (MS Windows deny this).

But anyway, today 'user' access should support user namespaces
(subuid/subgid)

This is required for rootless container development (podman, docker).

Another point is "sandbox model" by snap/flatpak.

In particular in "partial" supported scenarios: Snap+SeLinux (fedora)
and Flatpak+AppArmor (ubuntu)

Bug description:
  Binary package hint: debian-installer

  On a fresh dapper install i noticed that the file permissons for the
  home directory for the user created by the installer is set to 755,
  giving read access to everyone on the system.

  Surely this is a bad idea? If your set on the idea can we atleast have
  a option during the boot proccess?

  Also new files that are created via the console ('touch' etc.) are
  done so with '644' permissons, is there anything that can be done
  here? nautlius seems to create files at '600', which is a better
  setting.
