The symbols in /proc/kallsyms are .sys_inotify_init and .sys_signalfd,
not sys_inotify_init and sys_signalfd, so the preinst script thinks
they're not there.  I kludged around it by doing "sudo touch
/etc/udev/kernel-upgrade", but a better way would be to fix the
regexps in the preinst script.

The "." at the start of the symbol names is an ABI thing; ".foo"
refers to the start of the text for function foo, "foo" refers to the
procedure descriptor for foo.
