Subject: Remove persistent udev rules.
X-Git-Url: https://git.siccegge.de//index.cgi?p=forks%2Fvmdebootstrap.git;a=commitdiff_plain;h=91a3a806c22110ae2ec05f1f839e27ae00e01564

Remove persistent udev rules.

When debootstrap installs udev, it picks up at least the net devices
from the host that is building the image. This is not useful, so we
remove the files. Upon booting the image, udev will re-create the
files, so that's all fine.
