nope.
not in the slightest bit: i wish it did!!!
i'm using 2.6.8 [.1-selinux1 from http://sf.net/projects/selinux]

please tell me how i enable such functionality!
i remove a usb media, HAL does a umount -lf, konqueror still has
directory handles open (see report i sent earlier with the little
program opendir.c which duplicates what konqueror does), then HAL
does an ioctl("/dev/sdc1", Block_Re_Read_PARTition) which returns
an error message "Device or Resource Busy".
david (hal developer) considers this to be a serious bug in the
linux kernel because a user action can cause hotplug events to
not be generated.
the above ioctl is supposed to cause a hotplug event that will
allow HAL to remove the volume from its records.
and it can't.

Truth, honesty and respect are rare commodities that all spring from

around you, funnily and coincidentally enough, life gets a lot better.
