[Bug 1326049] [NEW] init script deletes /dev/ipmi0

[Benjamin Rodgers]

Public bug reported:

According to the init script, it deletes '/dev/ipmi0' whether or not
udev is in use for compatibility with kernels compiled for other
distributions.

# NOTES:
# * /dev/ipmi0 is unconditionally deleted here on ipmi_devintf unload,
#   because SLES9 and RHEL4 kernels don't send a message for udev to delete
#   it for us.

If you boot up with ipmi modules compiled into the kernel, the init
script will delete out '/dev/ipmi0' and never re-create it since it
tries to re-create the device by re-inserting the module.  I'm currently
working around this problem by using the same check for udev used
elsewhere in the script, and never deleting the device files in the
first place.


Here's some standard information about the distribution we're running on and package version.

And here's the small patch I'm currently using to work around the issue.
