[Virtual-pkg-base-maintainers] Bug#427469: /dev/null: permission denied

[Yawhen Kasarzhewski]

Package: base

I have very annoying bug: after a time, I am getting '/dev/null: 
permission denied', when working under user. Something changes /dev/null 
permissions.

Udev has proper permissions though.

root at warp:~# grep -r 'null' /etc/udev/
/etc/udev/rules.d/020_permissions.rules:KERNEL=="null",                 
MODE="0666"
/etc/udev/links.conf:M null             c   1 3
/etc/udev/permissions.rules:KERNEL=="null",                     MODE="0666"

I do chmod 666 /dev/null from root shell and can work some time, however 
after some hour-two I get this error again.

Noticed in Debian Etch i386 and amd64 and current sid amd64
