Subject: [PATCH] base: Don't wait for swap devices in host-only mode.
|
||
|
|
|
||
|
|
The only reason we add swap devices to host-only mode (added in
|
||
|
|
dd5875499ece9dbc90e10eafd0073ee15d0c86a4) is to allow us to process
|
||
|
|
resume= arguments passed on the kernel command line when the swap
|
||
|
|
partition lives on something slightly more complex than a normal
|
||
|
|
partion (e.g. in an LVM or RAID setup).
|
||
|
|
|
||
|
|
By adding the device to host_devs, the necessary LVM and RAID hooks
|
||
|
|
are added and thus the underlying storage will be initialised OK, and
|
||
|
|
the 95resume module handles the waiting for the device (via udev rules
|
||
|
|
creating the /dev/resume symlink).
|
||
|
|
|
||
|
|
So ultimately, we do not need to hard-code the waiting for the swap
|
||
|
|
devices into the initramfs at build time as the waiting part can be
|
||
|
|
dynamic.
|
||
|
|
|
||
|
|
This makes things more resiliant to swap partitions disappearing and
|
||
|
|
being reformatted etc.
|
||
|
|
|
||
|
|
