2010-02-21poll_device: do not wait for a device to appear if udevd is not runningThomas Bächler1-5/+7
Devices will never "magically" appear when udevd is not running. Thus, poll_device now exits instantly when a device when udevd is not running. The return value is unchanged, just the delay is removed. Assuming that the drive is available just after loading the module is unsafe. However, "fast" devices like most (all?) pata/sata seem to work this way for many people. On "slow" devices like USB, we still have to wait - those will not work without udev.
2010-02-21Allow the second parameter of poll_device to be 0 - this fixes rootdelay=0Thomas Bächler1-1/+1

exist on it, bail out instead of panicing In these cases, we will exec /bin/sh, such that manual recovery is still possible as sh has PID 1 An expert might be able to mount and switch_root manually. In any case, this is less scary than a panic and a useless trace.

2009-06-07Don't only check for block devices, but also for symbolic links.Thomas Bächler1-2/+2
If we have a symlink, we don't check further if it points to a block device, partially due to klibc's readlink being broken.
