Bug#387809: initramfs-tools: please increase sleep time on nfs retries

[Vagrant Cascadian <vagrant+bugs@freegeek.org>]

Package: initramfs-tools
Version: 0.79
Severity: minor

when using nfs, it sleeps for 0.1 seconds. it retries 180 times by
default. this means the server may get nearly 180 dhcp and nfs mount
requests in a little over 18 seconds, and while an individual client
doing this is no big deal, an entire network doing this could be
crippling.

please increase the delay to 1 second, or better yet, increase the retry
delay a little each failure, i.e. : 1 second 1st retry, 2 seconds 2nd
retry, 4 seconds 3rd retry, etc..

i'll work on some patches later...

live well,
  vagrant
