Subject: [ptxdist] [PATCH] rootfs: change permissions of initial device nodes according to LFS 6.1.1
Date: Tue, 16 Oct 2012 17:45:32 +0200	[thread overview]
Message-ID: <1350402332-25097-1-git-send-email-post@lespocky.de> (raw)

Non priviledged users could not write to /dev/null before. Checked the
correct permissions by looking at Ubuntu/Debian and LFS. The
permissions are maybe overwritten by udev, but on targets without udev
but static dev tree, this would prevent non-root users to access these
devices.
