Copies a subset of the files installed by the
do_install
task into the sysroot to make them available to other recipes.
Files that would typically not be needed by other recipes at build
time are skipped.
Skipped files include files installed into
/etc.
For information on what files are copied, see the
staging
class.
The do_populate_sysroot
task is a
shared state (sstate) task, which means that the task can
be accelerated through sstate use.
Realize also that if the task is re-executed, any previous output
is removed (i.e. "cleaned").
