Currently the tests fail on x86 with recent kernels: FAIL: test-255-disks.sh This confused me for a while because our other test program (utils/max-disks/max-disks.pl) reports that it should be possible to add 255 disks. Well it turns out that the default amount of appliance memory is sufficient if you're just adding disks, but if you try to add _and_ partition those disks there's

...behaviour certainly needs to be documented, eg. in guestfs(3), because it changes an assumption that setting TMPDIR will move every temporary file that libguestfs creates. Are there machines where /tmp is unusable? Should we provide an API to read the sockname, analogous to guestfs_get_tmpdir and guestfs_get_cachedir? Should we use /run or /dev/shm instead? I would say, not /run/user because systemd doesn't reliably create it, unfortunately, but maybe somewhere else in /run would be acceptable. How does libvirt handle socket paths? Does it put them in /run, and can we emulate its behaviour? Are there i...

I download libguestfs from github and fetch to the *origin master*. I tried to build libguestfs in my own linux distro and I followd the http://libguestfs.org/guestfs-building.1.html#using-a-prebuilt-binary-appliance to replace with supermin I download the appliance-1.30.1.tar.xz and appliance-1.30.1.tar.xz.sig and extract the tarball to /home/user/appliance and export
