[pkg-cryptsetup-devel] Bug#498964: udevsettle wait for timeout when cryptsetup called from udev rule

[Olivier Guerrier]

Package: cryptsetup
Version: 2:1.0.6-6
Severity: normal


I have some udev rules to automount some usb device and run cryptsetup,
it used to works seemlessly. (I've switched from etch a few weeks ago).

Now this rule take a loooooong time to complete. Litlle investigation showed
that cryptsetup call "udevsettle" which waits the udev queue to be empty...

Obviously this a not the case until udevsettle timeouts (180s later)...

Don't know exactly how to correct this the right way, this small patch do the
trick here at no cost, but is probably wrong in others use.
