Random number generation on the Gluglug x60

I am not sure if the following is a security concern for the default x60 configuration, but I noticed that the kernel on my Gluglug x60 appeared to have low entropy (~100) as measured by
cat /proc/sys/kernel/random/entropy_avail
I was able to raise this figure to a reasonable level (>1000) by installing an entropy gathering daemon as follows:
apt-get install haveged
Does anyone know if this is an actual concern or if there is a better way to boost entropy?
Since /dev/random blocks when it's out of entropy I think it's not an issue. It would just mean it takes longer to do things requiring lots of entropy but I suspect you're not generating GPG keys and stuff like that all of the time.

So use your keyboard, disk, etc. as normal since these are all inputs into the pool.
Right. That's the only time a game of Klondyke (Solitaire for Windows) makes sense. Mindlessly moving some pseudo-random distributed cards with the mouse and clicking away does help.
