When checking for the existance of /dev/mapper devices found in the fstab of a filesystem, using guestfs_exists means they are checked as files in the guest, while they really appear as devices on the appliance. Resort using a debug API to check whether a file in the appliance exists, instead. Fixes commit 96b6504b09461aeb6850bb2e7b870a0a4c2f5edf. --- src/inspect-fs-unix.c | 15 ++++++++++++++- 1 file cha...

Hi, this patch series improves the way /usr filesystems are handled: tag them appropriately, so later on we can find them and merge results they contain directly back for the root filesystem. Changes in v2: - removed patches #1 and #2, already pushed - drop patch #3, no more needed - replace patch #4 with a better suggestion from Rich - change if into assert in patch #5 Thanks, Pino Toscano

Hi, this patch series improves the way /usr filesystems are handled: tag them appropriately, so later on we can find them and merge results they contain directly back for the root filesystem. The series includes also a new private debug API, and its usage to fix the resolution of /dev/mapper/.. devices found in fstab; without it, LVM /usr filesystems are not recognized as belonging to their

The existing mechanism was clunky, slow and used ~ 10 MB of local disk. Rich.

Hi, I am using guestfish to write some files into guest file system of my KVM domain. As you know, I have to mount guest disk at a position in the filesystem before I write any files into it , e.g.: mount /dev/VolGroup00/LogVol00 / But the problem is how I can get guest filesystem info without login guest. Now I have to power on the KVM domain, login the guest, remember which

These three patches (two were previously posted) can do simple operating system inspection in C.

This patch series changes a small part of the library to use __attribute__((cleanup(...))) to automatically free memory when pointers go out of the current scope. In general terms this seems to be a small win although you do have to use it carefully. For functions where you can completely get rid of the "exit code paths", it can simplify things. For a good example, see the

This series fixes inspection in the case that fstab contains references to md devices. I've made a few changes since the previous posting, which I've summarised below. [PATCH 1/8] build: Create an MD variant of the dummy Fedora image I've double checked that no timestamp is required in the Makefile. The script will not run a second time to build fedora-md2.img. [PATCH 2/8] build:

Inspired by libvirt's virCommand* internal mini-library, this adds some internal APIs for running commands. The first patch contains the new APIs. The subsequent patches change various parts of the library over to use it. Rich.
