...false positive using rpart?

However, in the final tree, an important predictor is not retained. Moreover, another predictor contains missing values in 40% of samples. So I don't know if the important predictor is not retained as the result of missing values or if I should have sel...

As preliminary steps in splitting virt-p2v to an own repository, start making p2v more independent within libguestfs. This is accomplished by the following changes: - generate the p2v kernel config sources & docs at build time using a Perl script, rather than the generator (so no need for OCaml when building from git, and no generated sources in dist tarballs) - create two local test

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.

Hi, this series update libguestfs to a recent gnulib version, so that we can use its new getprogname module, and solve altogether one of the porting issues (the need for 'program_name' by the error module of gnulib), and have a single way to get the name of the current program. A number of changes in tools mostly, although mechanical. Thanks, Pino Toscano (3): Update gnulib to latest

These are a prelude to fixing https://bugzilla.redhat.com/show_bug.cgi?id=1590220 A lot of the virt-p2v configuration code was duplicated manually. These changes make sure that most of it is generated. Rich.

libguestfs has used double and triple underscores in identifiers. These aren't valid for global names in C++. (http://stackoverflow.com/a/228797) These large but completely mechanical patches change the illegal identifiers to legal ones. Rich.

Now that virt-p2v has its own repository [1] and releases [2], it is time to remove it from libguestfs.
