|
* parthelper.c: Helper program to talk to parted with.
|
|
*
|
|
* This helper exists because parted is GPLv3+, while libvirt is LGPLv2+.
|
|
* Thus we can't link to parted in libvirt.so without the combined work
|
|
* being GPLv3+. Thus we separate via an external command. NB, this source
|
|
* code is still LGPLv2+, but the binary helper is effectively GPLv3+
|
|
*
|
|
* The existing 'parted' command line tool is also incredibly hard to parse
|
|
* in a reliable fashion if merely after a list of partitions & sizes,
|
|
* though it is fine for creating partitions.
