Bug 75323 – netmount confused on shutdown if hotplug networks and/or manual nfs mounts present

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description Kevin F. Quinn (RETIRED) 2004-12-22 08:31:04 UTC]

Networks on my system are started via hotplug/pcmcia depending on what docking station is attached, and nfs mounts are manually made depending on what network it's connected to.  The only nfs mounts in /etc/fstab are 'noauto'.

netmount in baselayout-1.9.4-r6 doesn't cope with this well; as netmount gets shutdown after hotplug/pcmcia/portmap do.


Reproducible: Always
Steps to Reproduce:
1.Configure networks for hotplug only (i.e. net.eth0 is not enabled on boot or default)
2.Boot up.
3.Once up, manually nfs mount something
4.Shutwown

Actual Results:  
netmount is confused, at best timing out when trying to unmount the nfs mounts,
as the network is already down.


Expected Results:  
Shutdown netmount before hotplug/pcmcia and any network interfaces are shut down.

Attachment to follow, showing the patch to netmount I've made that works for me
so far.

Changes such that netmount goes down before networks do

Basically makes use of "after" for the various services that should go down
after netmount.

1) If no nfs mounts occur automaticaly, does "after portmap nfs" instead of
"need portmap" and "use nfs"

2) Puts all the network stuff in "after", so that networks go down after mounts
are unmounted.	I think "need net" is not sufficient.  Probably not the neatest
way to do this, but once it worked I stopped fiddling with it :)

3) Also, perhaps unnecessarily, puts "hotplug pcmcia" in "after"

FWIW it also adds 'cifs' to the rcfilesystems stuff - I believe this may
already be covered on other bugs.
