Package: ifupdown
Version: 0.6.4-4.9
Severity: important
Tags: patch
At the moment, the postinst script in ifupdown set up
/etc/network/run/ as a symlink to /dev/shm/network/. But the
/dev/shm/ file system is reserved for use by the shm* glibc functions,
and should not be used as a generic state storing area.
Recently, in version 2.86.ds1-23 of initscripts, the boot system in
debian was changed to provide /lib/init/rw/ as a writable tmpfs area
for scripts running early in the boot. ifupdown might run very early
in the boot, and would be better of using this area instead of
/dev/shm/. Here is an untested patch to move ifupdown over to use
this new tmpfs.
