Subject: [PATCH] rules: watch metadata changes in ide devices
|
||
|
|
|
||
|
|
Formatting IDE storage does not trigger "change" uevents. As a result
|
||
|
|
clients using udev API don't get any updates afterwards and get outdated
|
||
|
|
information about the device.
|
||
|
|
...

||
|
|
Creating filesystem with 262144 4k blocks and 65536 inodes

ls: cannot access '/dev/disk/by-uuid/98791eb2-2bf3-47ad-b4d8-4cf7e914eee2': No such file or directory

|
Include hd* in a match for watch option assignment.
|
||
|
|
|
||
|
|
Upstream-Status: Denied
|
||
|
|
|
||
|
|
qemu by default emulates IDE and the linux-yocto kernel(s) use
|
||
|
|
CONFIG_IDE instead of the more modern libsata, so disks appear as
|
||
|
|
/dev/hd*. A similar patch rejected by upstream because CONFIG_IDE
|
||
|
|
is deprecated.
