Subject: [PATCH] bootctl: properly sync fs before/after moving random seed
|
||
|
|
file into place
|
||
|
|
|
||
|
|
Let's do a careful, focussed sync at the right places instead of a
|
||
|
|
blanket sync at the end. After all we want to run this on every boot
|
||
|
|
soon.
|
||
|
|
|
||
|
|
(cherry picked from commit 60315d59534fe59aacae26e2c497359a409af0b6)
