partprobe BUG

From: Martin Raivio
Subject: partprobe BUG
Date: Wed, 7 Jun 2006 09:42:12 -0400 (EDT)

BUG: in the partprobe binary of parted
parted1.7.1 compiled on Slackware with kernel  2.6.13 gcc version 3.3.6
Also parted parted-1.6.25-8 on Fedora5.
On slackware I tried configure --enable-discover-only but then it would not

partprobe -sd /dev/hdb gives the result

Error: Error informing the kernel about modifications to partition /dev/hdb1
-- Device or resource busy.  This means Linux won't know about any changes
you made to /dev/hdb1 until you reboot -- so you shouldn't mount it or use
it in any way before rebooting.
Warning: The kernel was unable to re-read the partition table on /dev/hdb
(Device or resource busy).  This means Linux won't know anything about the
modifications you made until you reboot.  You should reboot your computer
before doing anything with /dev/hdb.

To me this seems a lot like a bug since by definition
-d   means  Don't update the kernel.
and partprobe isn't supposed to be modifying the partion. The fdisk
information about /dev/hdb gives the information

/dev/hdb1   *           1        2065    16586608+  a5  FreeBSD
Partition 1 does not end on cylinder boundary.

IE /dev/hdb1 has FreeBSD and the partition (as set up by Windows98) was
perhaps not absolutely correctly set up.

parted /dev/hdb print unit s print unit chs print
