[Bug 759725] Re: The kernel is no longer readable by non-root users


Since the vmlinuz-X.WY.Z-X-generic can be easily downloaded from the
Internet, this "by design" change makes Ubuntu less useful.

Ubuntu needs to make "IT things" (Linux) better for humans, not worse...

This is also afecting OpenStack... Reference:

  The kernel is no longer readable by non-root users

Status in “linux” package in Ubuntu:
  Won't Fix

Bug description:
  The mode of the latest kernel has changed so it is no longer readable
  by non-root users:

  -rw-r--r-- 1 root root 4336016 2010-10-17 01:37 /boot/vmlinuz-2.6.35-22-generic
  -rw-r--r-- 1 root root 4336912 2010-11-24 12:46 /boot/vmlinuz-2.6.35-23-generic
  -rw-r--r-- 1 root root 4523072 2011-03-08 18:47 /boot/vmlinuz-2.6.38-6-generic
  -rw------- 1 root root 4523936 2011-04-11 05:24 /boot/vmlinuz-2.6.38-8-generic

  This prevents people from using this kernel to boot qemu
  virtual machines as non-root.

  Please change the mode back to make the kernel readable.
