you have nameserver as localhost but the nameserver is listening on yer 10 net. Shouldnt also indicate that check files first then network? I am not as familiar with the Debian as I should be. [link|http://packages.debian.org/changelogs/pool/main/i/ifupdown/ifupdown_0.6.4-4.8/changelog|http://packages.debi...6.4-4.8/changelog]

ifupdown (0.6.4-4) unstable; urgency=low

* Don't delete /etc/network/ifstate every boot, just empty the file. This
way people can symlink it to /var/run/ifstate if they so desire (ie, if
/var is local and /etc is read-only). (Closes: Bug#103868, Bug#85206)
* Explicitly set PATH in the environment, because pdksh is broken, broken
I say. (Closes: Bug#83557, Bug#99444)

so if yours is doing this, a package dep has been changed?
thanx,
