Description Robin Green 2008-02-26 23:33:21 UTC

Description of problem:
/etc/modprobe.conf grows quickly (exponentially?) every time it is edited by
system-config-network, if it has a certain style of comments already in it. This
causes slowdowns.

Version-Release number of selected component (if applicable):
system-config-network-1.4.7-1.fc8

My /etc/modprobe.conf grew to 12MB which is a bit too large to attach to
bugzilla. Here is the head of it:

I think it's obvious here what is going wrong. The comment is being duplicated -
I suspect by some code in system-config-network.

Comment 1 Robin Green 2008-02-26 23:35:16 UTC

Of course, it could instead be the fault of the hsf installer, which I also ran
several times. I am not sure, because I do not remember if modprobe.conf was
this large before I ran system-config-network.
