The mbrlabel line is the one that populates the in-core label from the
MBR partitions on disk, including extendeed partitions. Normally, when
the kernel fabricates an in-core label for a non-NetBSD disk, it only
looks at primary partitions.

By default the in-core label is forgotten and reconstructed each time
a disk is last closed and reopened; this is useful with removable
media, for example.  The sleep trick keeps an open filedescriptor to
the disk, and prevents this happening.

See my other post for how to change the default label-forgetting
behaviour.
