Subject: [PATCH] grub-switch-to-blscfg: Use install to copy GRUB binary,
|
|
modules and config
|
|
|
|
By default the cp command truncates the destination before copying from the
|
|
source, so if interrupted it can lead to a file that's half written.
|
|
|
|
This behavior can be modified using the --remove-destination option, but is
|
|
usually a better choice to use the install tool for this. So let's do that.
