There was some=20 disagreement about what "dangreously dedicated" means. Does it mean=20 getting rid of the DOS partition table (slices?) Or, does it mean=20 creating a slice or disks without BSD partitions? The Handbook (18.3)=20 says: "If the disk is going to be truly dedicated to FreeBSD, you=20 can use the dedicated mode. Otherwise, FreeBSD will have to live=20 within one of the PC BIOS partitions. FreeBSD calls the PC BIOS=20 partitions slices so as not to confuse them with traditional BSD=20 partitions."=20 The programer in charge of the change seemed to indicate that the=20 "Dangerously dedicated" mode (I assume that means no BSD partititons)=20 conflicts with "GEOM: Modular Disk Transformation Framework." GEOM=20 appears to be an asbtraction layer for accessing various disks. With=20 the move underway to start accessing all disk as SCSI(3 is device=20 independent (with translation help)) devices, it probably makes for=20 more elegant code. Handbook (19.2 GEOM Introduction) reads: "GEOM permits access and control to classes -- Master Boot Records,=20 BSD labels, etc -- through the use of providers, or the special files=20 in /dev. Supporting various software RAID configurations, GEOM will=20 transparently provide access to the operating system and operating=20 system utilities."=20 The important thing in that quote is that "BSD labels" (and Master=20 Boot Records) are mentioned specificly.=20 Regards, James Phillips=0A=0A=0A ______________________________________________= ____________________=0AYahoo!
