Subject: [PATCH] lsinitrd: list squash content as well
|

|
|

When the initramfs is built with squash module enabled, the content
|
|
|
9f65cc |
inside squash image will be invisible from the lsinitrd tool. This
|
|
|
9f65cc |
commit make lsinitrd detect and list the content of the squash image as
|
|
|
9f65cc |
well to avoid possible confusion.
