Subject: Added two sanity checks:
X-Git-Tag: v3.1.0~322
X-Git-Url: http://zhaoyanbai.com/repos/Bv9ARM.ch07.html?a=commitdiff_plain;h=0ab4039806f5e8e16a4723dd16c349f2d12cb818;p=minix.git

Added two sanity checks:
	.  partitions larger than the disk
	   (this happens when partitions are set to end earlier than they start
	   in part)
	.  zero-sized partitions (this confuses autopart later on)

autopart doesn't continue if this happens.
