similar to: [PATCH supermin v4] Supermin 5 rewrite.

Obviously for very large files this is going to be a problem, as well as not being very cache efficient. libext2fs can handle writes to parts of files just fine so copy files in blocks. Also demote the "Permission denied" error to a warning, and add some explanatory text telling people not to use sudo. --- src/ext2fs-c.c | 127 +++++++++++++++++++++++++++++++++++----------------------

The ext2 filesystem on disk format has two ways to store symlinks. For symlinks >= 60 bytes in length, they are stored as files (so-called "slow symlinks"). For shorter symlinks the symlink is stored in the inode ("fast symlinks"). Previously we only created slow symlinks even if they are shorter than 60 bytes.

From: "Richard W.M. Jones" <rjones@redhat.com> This plugin allows you to create a complete ext2 filesystem in a GPT partitioned disk image. This can be attached as a disk to a Linux virtual machine. It is implemented using libext2fs (the same as supermin). Although there is some overlap with nbdkit-iso-plugin and nbdkit-floppy-plugin, the implementations and use cases of all

Add a --size option to setting the size of the ext2 filesystem, so it is possible to create ext2 appliances with smaller disk images. The default is like the previously hardcoded value of 4GB. --- src/build.ml | 4 ++-- src/ext2.ml | 19 ++++++++++--------- src/prepare.ml | 2 +- src/supermin.ml | 9 +++++++-- src/supermin.pod | 15 +++++++++++++++ 5 files changed, 35

We created symlinks in two steps, by creating the empty inode and then calling ext2fs_symlink to populate it. This created broken symlinks where the directory name contained a / character, eg: lrwxrwxrwx 1 root root 7 Nov 26 08:43 /bin -> usr/bin lrwxrwxrwx 1 root root 7 Nov 26 08:43 /lib -> usr/lib lrwxrwxrwx 1 root root 9 Nov 26 08:43 /lib64 -> usr/lib64 lrwxrwxrwx 1

Hi Rich Kindly ignore my previos mail. I have downloaded the latest version of supermin supermin-5.1.8 and have compiled it for powerpc.Moreover there was no need to patch the src/ kernel.ml file as the changes were already implemented on the latest version. But still when i run libguestfs-test-tool on powerpc ubuntu,I get the below logs.. libguestfs-test-tool

This two-part patch for supermin implements device trees (for ARM). The first patch introduces a more rational way to handle command line arguments in 'supermin-helper'. See the commit message for details. The old style is still supported for compatibility. The second patch adds an extra supermin-helper --dtb parameter specifying a wildcard. A device tree file which matches the

Thanks for your response Rich. Please see the output of --trace --verbose below. Regarding your suggestion to convert the vmdk to some other format, I do not want to do it. A security consultant said by modifying certain files in our VM and restarting the VM, one can gain access to encrypted data in our VM. I want to reproduce it. I am able to mount the VM but not able to modify files since it can

Hi Rich, I ran coverity against febootstrap's head and it spotted four leaks. This fixes them. The first patch plugs three. The second attempts to make the add_link function do what I'm guessing it was intended to do. As is, it was a no-op. >From 7c2ff55613598a1295e213cef36600ad61da7ed6 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering at redhat.com> Date: Tue, 10 Jan 2012
