Subject: [PATCH] busybox module: parse busybox defined functions dynamically
|
||
|
|
|
||
|
|
Currently in dracut busybox module, we hard-code the list of binaries
|
||
|
|
available in busybox. Actually we can get this list by running busybox
|
||
|
|
without any arguments.
|
||
|
|
|
||
|
|
Also, if find_binary() finds nothing, we would symlink $initdir/
|
||
|
|
which is not we expect.
