Description of problem:
On my F-8 i386 default dvd-install and F8 x86_64 live cd install both I have:
[hans@localhost ~]$ lsmod | grep loop
loop 16581 0
Even though there is no reason for loop.ko to get loaded, on the x86_64 I
checked initrd and it is not the culprit.
udev does not load loop.ko it just created /dev/loop[0-7] manually
if s.th. opens /dev/loop[0-7] the loop module gets autoloaded by the kernel.
on my F8 laptop loop.ko is not loaded at all
you might do a lsmod check in rc.sysinit at several points to find the culprit..
Reopening, this is a bug, reproduced on 2 completely different systems. I'll do
the lsmod thingie as time allows and get back to you.
Added lsmod commands, this indeed is not caused by udev, changing component to
intiscripts for now. The unneeded loading of loop.ko is triggered by these 3
lines in rc.sysinit (circa line 465):
if [ -x /sbin/lvm.static ]; then
action $"Setting up Logical Volume Management:" /sbin/lvm.stati
So systems where this does not show up are probably not using device-mapper
which is strange as that is the default when autopartitioning. I would really
expect Fedora developers to be using a setup identical to the default setup (eat
your own dogfood principle).
Heh, I tested on a single drive laptop, where LVM is sort of pointless.
Assigning to lvm, regardless.
Well lvm scans devices to search for physical volumes - could that be causing
this perhaps? Add -vvvv to the command and capture the ouput and see if it's
opening them. Thing is, lvm has got to do that - in general, there might be PVs
there. If you know better, then you can configure lvm to ignore loop devices by
putting a filter into the lvm.conf file - see if that stops it.
Found it, adding:
# Exclude the loop devices
filter = [ "r/loop/" ]
To /etc/lvm/lvm.conf fixes this. Are there any configurations conceivable where
there will be lvm on the loop devices? Maybe crypto setups?
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '8'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 8's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 8 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
