Yes. A hash function is any

Hi people,
I've been trying to set up a volume group on a partition on an IDE hard drive
(a
Western Digital 80 GB) at /dev/hda. I am doing this by issuing the command
pvcreate /dev/hda4. However, instead of creating the physical
volume, an error
is returned: Failed to create regex device filter.

hi!
First of all - I also think that this is nothing security related!!!
maybe ltrace it? Because I don't think the error message comes from
pvcreate:
strings `which pvcreate` | grep regex
(yields nothing)

Again, my apologies to all for posting my query up on the wrong news list.
Just to tie off the thread, it was pointed out to me from reading the source of
the LVM2 tools, that pvcreate may have been failing due to a misconfiguration in
/etc/lvm/lvm.conf - it's failing to set up a filter for the
