Build drivers tree on installation so kernel modules can be found on first boot after installation (otherwise the modules would be available too late, after initial installation of the kernel has happened while seeding). Also, make sure that the tree is not re-created when seeding, and add a spread test for kernel-modules components. * dirs: add function to get root of drivers trees * kernel: do not recreate drivers tree if it already exists On installation, a drivers tree has already been copied to the data partition. Do not re-create if found when seeding happens (note though that on preseeding we will not find the tree and we will still create it). * gadget/install: create device tree on installations Create a device tree on installation so we have it on first boot. * o/snapstate: fix task message * tests/nested/manual: add kernel-modules-components test This test installs a kernel-modules component and verifies that the shipped kernel module is installed and can be loaded. * tests/lib: do not error out if cloud-init finished with 'recoverable error' status. * kernel: have destination as argument when building drivers tree We need to tackle the generic installation case as opposed to creating the drivers tree when seeding the system. In that case the destination tree can vary depending on installation type. * overlord: pass kernel information to install package so the drivers tree can be created. * cmd/snap-bootstrap: build drivers tree on installation from initramfs * tests: adapt to additional parameters in install.Run * snap/naming: add ancillary method to split a full component name into snap and component names. * gadget/install: fix nosecboot tests
