Got these in my daily run output due to background fsck's
today after power outage in data center. Not sure if they are
new or not, so I'm just posting them.

dmesg follows in case it's needed. LOR's show up at
bottom of this too.

Sleep sweet within this quiet room,
O thou, whoe'er thou art,
And let no mournful yesterdays
Disturb thy peaceful heart.
Nor let tomorrow mar thy rest
With dreams of coming ill.
Thy maker is thy changeless friend,
His love surrounds thee still.
Forget thyself and all the world,
Put out each garish light:
The stars are shining overhead -
Sleep sweet! Good night! Good night!
