I've been experimenting with livecd-creator and my first run failed because I had TMPDIR=/t/jt7300.Wu7340. [btw, this is on rawhide x86_64, with latest cloned from git] I did this: ./livecd-creator \ --config=/usr/share/livecd-tools/livecd-fedora-minimal.ks \ --cache=/tmp/livecd-cache When I reran it with a more conventional TMPDIR, it completed successfully: TMPDIR=/tmp ./livecd-creator \ --config=/usr/share/livecd-tools/livecd-fedora-minimal.ks \ --cache=/tmp/livecd-cache FYI, here's how it failed: Building an initramfs at /boot/livecd-initramfs-2.6.23.1-42.fc8.img for kernel 2. 6.23.1-42.fc8 mktemp: cannot make temp dir /t/jt7300.Wu7340/tmp.RfvfM24995: No such file or dir ectory Traceback (most recent call last): File "/home/meyering/w/co/livecd/creator/livecd-creator", line 1603, in <module sys.exit(main()) File "/home/meyering/w/co/livecd/creator/livecd-creator", line 1575, in main target.install() File "/home/meyering/w/co/livecd/creator/livecd-creator", line 959, in install self.configureBootloader() File "/home/meyering/w/co/livecd/creator/livecd-creator", line 1230, in configu reBootloader %(self.build_dir, count)) File "/usr/lib64/python2.5/shutil.py", line 46, in copyfile fsrc = open(src, 'rb') IOError: [Errno 2] No such file or directory: '/var/tmp/livecd-creator-zHqhMn/ins tall_root/boot/livecd-initramfs-2.6.23.1-42.fc8.img' [Exit 1]
