[Pkg-sysvinit-devel] Bug#499796: initscripts: rootfs over nfs hangs at reboot

Package: initscripts
Version: 2.88dsf-13.1
Severity: normal

The following problem happens reproducible in a network of 100 virtual
machines and a network of 120 "real" machines that mount their rootfs
over nfs.

When /etc/init.d/reboot is run and "reboot -d -f -i" called, in about
2-4% of the cases, the system will deadlock because the network
interfaces are shut down but the kernel still wants to read/write
something on the nfs export. The message "nfs server not responding" is

1) remove the "-i" from the init script
2) move the parameters to /etc/default/reboot

Please raise the severity to important, as the deadlock issue is serious
and custom modifications to the init script will be lost on package updates.
