[Bug 1126314] [NEW] Debootstrap is very slow. Please use eatmydata to fix this.

[Phillip Susi]

Public bug reported:

Debootstrap is very, very slow.  I watched a server install crawl by for
something like an hour at a rate of about 1 package per second.  A
simple debootstrap chroot takes 10 minutes to setup, with a
predownloaded tarball.  This slowness is due to dpkg making excessive
use of fsync().  Requests to fix dpkg in the past have been rejected and
I was told to use eatmydata.  After patching debootstrap to add
eatmydata to the required list, and activate it during the second stage
install, the time to construct the chroot dropped from 10m to 2m.  This
should also make installing new systems MUCH faster.
