Re: [uml-devel] /dev/fd/62: No such file or directory

Hi !
I have dig into this and made a repro-case:

#!/bin/bash
while IFS=- read line ; do
 echo $line
done < <(cat /etc/hosts)

on HOST this prints the contents of /etc/hosts
on UML this gives:
./test: line 4: /dev/fd/62: No such file or directory

it seems,  bash process substitution has problems within UML (at least within my uml)

i have googled a little bit - maybe this gives a hint:

http://groups.google.de/groups?hl=de&lr=&ie=UTF-8&th=94e9a60998cb724c&rnum=3

anybody able to reproduce ?

my UML is 2.6.6  (but i have seen this on other 2.6.x, too) - it uses devfs
host seems irrelevent - i have seen this on 2.4 and on 2.6 hosts

roland

Hi !
I`m getting the following errors with uml 2.6.6 (2.6.4 had that, too) and suse9 rootfs during boot (see below).
can anybody give me a hint, what`s the problem, and how to (probably) fix this ?
networking basically works - but i have to setup the defaultroute manually afterwards and soooo many errors during boot really don`t
give a good "feeling" :)

regards
roland
