Subject: Fix bug #13205: better random-seed entropy - For the random-seed file
 location to be more "FHS compliant" is better to put in
 /var/lib/misc/random-seed (Variable state   information, that persists after
 reboot) than the /var/run/random-seed (Run-time variable data, that not
 necessarily persists   after reboot) for example with /var/run mounted as
 TMPFS. - The random-seed file permision should be "0600" not "0644" - The
 size of random-seed acording to random(4) manpage should be the size
 specified in "/proc/sys/kernel/random/poolsize" in   other case 512 bytes.
