Keeping chroots small is important if you have many of them.
I just removed several, and free space went up from 20%...

# df    
Filesystem     1K-blocks     Used Available Use% Mounted on
udev            32908632        0  32908632   0% /dev
tmpfs            6591596    10664   6580932   1% /run
/dev/sdb5      125756780 94771244  24554408  80% /

...to 48% after that cleanup.

/dev/sdb5      125756780 61949636  57376016  52% /

The chroots are the biggest things on this partition:

#du -ax / | sort -n -r | head -n 20 |less

Of course, I could make the partition larger, but then I'd
just have more clutter.
