The first patch preserves file mode, UID, GID and SELinux context across edited files. The second patch adds a useful new command in guestfish ('llz') which shows SELinux context (like 'ls -laZ') that was useful when debugging this. Rich.

Add the new API btrfs-fsck to check the btrfs filesystem. Btrfs is currently under heavy development, and not suitable for any uses other than benchmarking and review.

A NEW API blkid. It can print the device attributes. Use it after list-devices, we can list ower devices and the attributes of each device. Use it like: blkid <device> It's should be a usefull function, and needed no test case for it.

Add xfs_info to show the geometry of the xfs filesystem. Signed-off-by: Wanlong Gao <gaowanlong at cn.fujitsu.com> --- Hi Rich, This patch add xfs_info, and start the xfs support work. I'd like to add the xfs support, like xfs_growfs, xfs_io, xfs_db, xfs_repair etc. Any thoughts? Thanks, Wanlong Gao daemon/Makefile.am | 1 + daemon/xfs.c | 69

This miscellaneous patch adds bindings for: - ntfsfix - ntfsclone - ntfslabel and unifies filesystem label setting through a single API 'set-label' which replaces 'set-e2label' and is also able to set labels on NTFS using the ntfslabel program. 'ntfsfix' has been added as a possible way to fix RHBZ#797760. However I have not found a way to fully fix this bug. See

I''ve filed this bug under util-linux, because I think wipefs isn''t deleting all btrfs metadata it could. But ultimately it appears to be a btrfs bug because nothing else sees the stale volume. https://bugzilla.redhat.com/show_bug.cgi?id=889888#c15 btrfs-progs-0.20.rc1.20121017git92d9eec-1.fc18.x86_64 e2fs-progs-1.42.5-1.fc18.x86_64 kernel 3.7.1-2 Brand new 80GB virtual disk,

https://bugzilla.redhat.com/show_bug.cgi?id=907554 In particular comments 2 & 3. We could change libguestfs's guestfs_mkfs (internally) so it always does an implicit wipefs on the filesystem. wipefs is not too onerous -- in particular I believe it only writes to a few chosen areas of the disk. Especially considering that we're about to run mkfs anyway which for some filesystems

Currently any api which takes a FileIn or FileOut parameter is implicitly cancellable. This change make cancellable an explicit flag in anticipation of it being added to other apis. --- generator/generator_actions.ml | 53 ++++++++++++++++++++++++++------------- generator/generator_checks.ml | 3 +- generator/generator_types.ml | 1 + 3 files changed, 38 insertions(+), 19 deletions(-)
