The DiskBuilder class is able to build a disk its corresponding
format and the installation image to install this disk by using
the InstallImageBuilder. However all three tasks were handled
in a row which lead to the problem that resources like active
mount processes were still open when e.g the disk format is
created. The race conditions produced here lead to an undefined
state of the resulting disk format and/or install image. In
order to avoid this the DiskBuilder class has been refactored
in a way that each tasks is an atomic operation which is
freeing its resources after success
All mkdtemp created directories are created with the 'kiwi_'
prefix. In addition all code parts which leaves tmpdirs in
the system after kiwi is done were fixed
nose is no longer maintained, thus we have to move to another
testing system. This commit updates the tox setup and all tests
to use pytest instead of nose.
As of today only the kiwi initrd could be used with an image
build. This commit adds a new initrd_system attribute and
allows to select between kiwi and dracut as initrd system.
Please note the dracut initrd does not support all features
of the kiwi initrd. This fixes#25
Make a factory out of the task and allow to have e.g
a dracut boot image task at a later point in time.
The BootImageBase class creates an interface for this
implementation. So far only BootImageKiwi is implemented
