Re: Hi,a little question about DP2.

Dear Wollman,

From: Garrett Wollman <[EMAIL PROTECTED]>
For backwards compatibility, the FreeBSD 4.x kernel would fake up the
partition tables so that they would look like old (pre-slicing)
FreeBSD partition tables; i.e., the starting offset of the slice would
be subtracted from all of the partition offsets on read and added back
in on write.  The disk partitioning subsystem in 5.x doesn't do this.

Thank you!
I also want to know if I want use LVM(Logical Volume Management), I need create
pseudo-device in "/dev". How can I do?
In 4.x, I can use 'disklabel' to change partition's size, offset and type, but in Current, I coudn't do that.
i.e. # disklabel -e /dev/da1s1
disklabel: ioctl DIOCGDINFO: Inappropriate ioctl for device
but the 'da1s1' device-name exists in '/dev'.
For my old experience in DP1, I compile kernel with option 'NO_DEVFS', so I can
create pseudo-device as in 4.x.
Whether I must use DP2 without DEVFS to use LVM?
Best Regards
Ouyang Kai
