Description Alexandre Oliva 2004-02-24 08:45:24 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040217

Description of problem:
modprobe -c | grep eth0 used to print only:

alias eth0 <module>

now it prints the line above plus:

install eth0 /bin/true

This may cause problems to
/etc/sysconfig/network-scripts/network-functions:is_available(), that
runs:

    alias=`modprobe -c | awk "/^(alias|install) $1 / { print \\$3 }"`
    if [ -z "$alias" -o "$alias" = "off" -o "$alias" = "/bin/true" ]; then

it doesn't expect two lines of output, and actually fails, printing
confusing error messages because of this.

Version-Release number of selected component (if applicable):
modutils-2.4.26-5

How reproducible:
Always

Steps to Reproduce:
1.modprobe -c | grep eth0

Actual Results:  If there is an entry for eth0 in /etc/modprobe.conf,
you get two lines, one from /etc/modprobe.conf, one from
/etc/modprobe.conf.dist, the second being a dummy install /bin/true line.

Expected Results:  Just the alias line in /etc/modprobe.conf
