Subject: [PATCH] kernel-install: add new variable
|
|
|
aa0848 |
$KERNEL_INSTALL_INITRD_GENERATOR
|
|
|
aa0848 |
|
|
|
aa0848 |
The idea is that when not set, we do whatever we did in the past. But
|
|
|
aa0848 |
with a new setting of initrd_generator=mkosi-initrd, mkosi-initrd will
|
|
|
aa0848 |
generate an initrd.
|
|
|
aa0848 |
|
|
|
aa0848 |
(cherry picked from commit 5c1b257faf87cb4f93aee8866f45a8cb98230af9)
