Description hhaygood 1999-08-08 23:40:50 UTC
System is stock RHL6.0/Intel.  Noticed problem after
building 2.2.10 from pristine source, don't know if it's

/etc/sysconfig/network-scripts/ifup-post, lines 20-22 read:

if [ "$ISALIAS" = no ] ; then
    /etc/sysconfig/network-scripts/ifup-aliases ${DEVICE}

Thus, it's trying to bring up alias interfaces when it
explicitly knows that there are none.  Only effect on my
system is to cause modprobe errors ("modprobe: can't locate
module eth0:0" [to eth0:49]),
but I suspect that this will cause fairly major hassles for
those who do use alias interfaces.  (The converse of the
effect that I see is that interfaces that include aliases
will not be properly brought up.)

Simple fix is to replace "no" with "yes" on line 20.  It
appears to work just fine for me, and makes sense logically.

That's not how it works. The 'ISALIAS' checks to see whether
the current interface is an alias; because you don't want
to bring up interfaces for an alias.

The problem is that you compiled the kernel without aliasing
support, and linuxconf's behaviour in this case is not very
good (it's what's causing these messages). Either comment
out the portion of ifup-aliases that refers to linuxconf, or
upgrade to the latest initscripts in Raw Hide, which has this
already done.
