I'm wondering what the best way of building a UML image is; I tried the following based on documents I found on the web for FC2 mkdir -p $T/etc $T/dev $T/proc $T/sys $T/var/tmp $T/var/cache/yum \ $T/var/lock/rpm $T/var/cache/yum/update/headers \ $T/var/cache/yum/update/packages touch $T/etc/fstab mknod $T/dev/null c 1 3 chmod 666 $T/dev/null mount --bind /proc $T/proc mount --bind /sys $T/sys rpm --root $T -Uvh --nodeps --force $UML/RPM/centos-release-4-4.2.i386.rpm \ $UML/RPM/yum-2.4.3-1.c4.noarch.rpm yum -y -C --installroot=$T groupinstall "Base" ($T is a temp directory; $UML is where I'm storing my software) Unfortunately yum fails to run, complaining about repomd.xml files being missing. + rpm --root /var/tmp/bld.13824 -Uvh --nodeps --force /usr/local/uml/RPM/centos-release-4-4.2.i386.rpm /usr/local/uml/RPM/yum-2.4.3-1.c4.noarch.rpm warning: /usr/local/uml/RPM/centos-release-4-4.2.i386.rpm: V3 DSA signature: NOKEY, key ID 443e1821 Preparing... ########################################### [100%] 1:yum ########################################### [ 50%] error: %post(yum-2.4.3-1.c4.noarch) scriptlet failed, exit status 255 2:centos-release ########################################### [100%] + yum -y -C --installroot=/var/tmp/bld.13824 groupinstall Base Setting up Group Process Setting up repositories Cannot open/read repomd.xml file for repository: update Cannot find repomd.xml file for update Error: Cannot find repomd.xml file for update (The yum rpm install problem is because chkconfig doesn't exist; not a problem.)
