Hi there, I'm running Yum 3.0.1 and RPM 4.4.2 under Debian and I am trying to bootstrap RPM based systems with mach which will generate a yum.conf like this: [main] cachedir = /../../../../../var/cache/mach/centos-4-i386/yum reposdir = /../../../../../var/lib/mach/states/centos-4-i386-os/yum/yum.repos.d under /var/lib/mach/states/centos-4-i386-os/yum.conf to bootstrap a chroot starting with: yum -c /var/lib/mach/states/centos-4-i386-os/yum.conf --installroot=/var/lib/mach/roots/centos-4-i386-os -y -y install bash glibc Yum processes happily to downloading, dependencies solving etc., but barks at the RPM transaction set run: ... warning: termcap-5.4-3: Header V3 DSA signature: NOKEY, key ID 443e1821 Finished Transaction Test Transaction Test Succeeded Running Transaction error: can't create transaction lock on /var/lib/rpm/__db.000 I simply don't have /var/lib/rpm (geez, I'm running Debian :-P). I think it would make the most sense to let Yum use the chroot's RPM db. I believe Yum correctly sets RPM's --root via the Python bindings of RPM, but I think it doesn't set --dbpath properly. Setting %_dbpath in /etc/rpm/macros before running mach, like below: %_dbpath /var/lib/mach/roots/centos-4-i386-os/var/lib/rpm works like a charm, but is terribly ugly. Should Yum be changed to set --dbpath when --installroot is set? Or should Yum support some way to set any RPM macro via yum.conf? The ML archives suggest this question was asked frequently; perhaps it should be promoted to the FAQ. Thanks for comments, -- Lo?c Minier <lool@xxxxxxxx>
