Change subject: Workaround for mdadm boot-time race condition
......................................................................
Workaround for mdadm boot-time race condition
The boot-time race condition assembling raid devices reported in T131961
can be avoided by sleeping a few seconds in initramfs-tools' local-top
stage, after which the root device is expected to be present.
See FAQ 26. in /usr/share/doc/mdadm/FAQ.gz.
