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

From: "Richard W.M. Jones" <rjones at redhat.com> If the parent process uses a pipe (or any fd, but pipes are a particular problem), then the recovery process would hold open the file descriptor(s) of the pipe, meaning that it could not be fully closed in the parent. Because the recovery process doesn't use exec(2), this wasn't avoidable even using FD_CLOEXEC. Avoid this

Hi, attached there is the second version of the patch series adding copy_in and copy_out in the library, mostly moving them from guestfish. It also adds the copy_in usage in virt-customize, as aid in a new image building. Thanks, Pino Toscano (7): cmd: add a way to run (and wait) asynchronously commands cmd: add a child-setup callback cmd: add the possibility to get a fd to the process

...ot;sparse" (making it consistent with qcow2). For qcow2, this allows "sparse" as a synonym for "off". It also adds "full", which corresponds to fully allocated, but uses posix_fallocate(3) for efficiency. "guestfs_tar_in": new "xattrs", "selinux", "acl" parameters.

https://bugzilla.redhat.com/show_bug.cgi?id=847880 https://bugzilla.redhat.com/show_bug.cgi?id=847881 This patch series adds various optional arguments to the tar-in and tar-out commands. Firstly (1/7) an optional "compress" flag is added to select compression. This makes the calls tgz-in/tgz-out/txz-in/txz-out deprecated, and expands the range of compression types available.

I thought it would be easy to rewrite virt-make-fs in C. Two days later ... The Perl program uses a lot of external commands, which makes it pretty tedious to implement in C. Rich.
