This patch series contains fixes and improvements we've made to several init 
scripts.  These changes have been thoroughly tested on Dylan and ported to 
master.

The following changes since commit 846bc50fde11bbb36c8eb5b2e3ae6bb644c037f3:

[PATCH 1/5] initscripts: bootmisc.sh: Make sysctl -p honor VERBOSE

[Ben Shelton]

From: Richard Tollerton <rich.tollerton@ni.com>

busybox sysctl may lack the "-q" setting, so simulate it with redirects.

[PATCH 2/5] initscripts: save /etc/timestamp with seconds accuracy

[Ben Shelton]

From: Blair Elliott <blair.elliott@ni.com>

Currently, /etc/timestamp is saved with minutes accuracy.  To increase
the accuracy, modify the save-rtc.sh and bootmisc.sh scripts to save and
read /etc/timestamp respectively with seconds accuracy.

[PATCH 3/5] initscripts: parametrize random seed file location

[Ben Shelton]

From: Richard Tollerton <rich.tollerton@ni.com>

Currently, the random seed file location is hardcoded to
/var/lib/urandom/random-seed.  Refactor it to a parameter
(RANDOM_SEED_FILE) so the file location is defined in only one place.

[PATCH 4/5] initscripts: Use current date as an additional source of entropy

[Ben Shelton]

From: Ken Sharp <ken.sharp@ni.com>

If the seed file is empty or does not exist, the date is an extremely
poor backup source of entropy, but it is better than nothing.

[PATCH 5/5] initscripts: make hostname.sh coreutils-compatible

[Ben Shelton]

From: Richard Tollerton <rich.tollerton@ni.com>

inetutils and busybox hostname utils support `hostname -F`; coreutils
hostname doesn't. So just use `cat` instead.

We also initialize it in the image.bbclass, you may want to tweak that one.

Since we deal with readonly it's possible it won't get updated after the 
image creation.

Will this work if procps's sysctl is used instead, I think it will but 
wanted to verify it.

Yes, it will work.  I just installed the procps package on an ARM target
and verified that the output is as expected for both settings of
VERBOSE.
