Re: [Libguestfs] [PATCH 3/3] v2v: bootloaders: improve detection of Grub2 default method

Detect only once which method must be used to get and set the default Grub2 kernel in the guest: this avoids the same checks in list_kernels and set_default_kernel. Also, add a "no method" option as well: Debian/Ubuntu guests do not have neither grubby nor Perl's Bootloader::Tools, so there is no way to know what is the default kernel, nor to change it. In this case, add a warning about this situation. --- v2v/linux_bootloaders.ml | 61 ++++++++++++++++++++++++++++++++++-------------- 1 file changed, 44 insertions(+), 17 deletions(-)
