[Bug 803739] Re: value set in /etc/sysctl.conf not used at boot time

Hi Yves,
  OK that means most stuff is working as it should; I think stop/waiting for procps is normal - it just does its setup stuff and stops again.

  Two thoughts then; I wonder whether at the time procps runs during
startup wlan0 has been found yet?  If it's not then I guess
/proc/sys/net/ipv6/conf/wlan0 might not be there yet.The other thought
is maybe something is setting it back after procps has run - but I think
that's less likely.

Dave

Title:
  value set in /etc/sysctl.conf not used at boot time

Status in “procps” package in Ubuntu:
  New

Bug description:
  This is at the bottom of my /etc/sysctl.conf

  net.ipv6.conf.all.use_tempaddr = 2
  net.ipv6.conf.wlan0.use_tempaddr = 2
  net.ipv6.conf.eth0.use_tempaddr = 2
  net.ipv6.conf.eth1.use_tempaddr = 2

  
  Yet, after a reboot:
  $ sysctl net.ipv6.conf.wlan0.use_tempaddr
  net.ipv6.conf.wlan0.use_tempaddr = 0
  $ sysctl net.ipv6.conf.eth0.use_tempaddr
  net.ipv6.conf.eth0.use_tempaddr = 2

  then as root:
  # sysctl net.ipv6.conf.wlan0.use_tempaddr=2
  net.ipv6.conf.wlan0.use_tempaddr = 2

  This is on Ubuntu 11.04 64 bit. This behaviour does not happen on
  Ubuntu 10.10 32 bit.
