Luigi Rizzo 60cf2c1254 Export a (machine dependent) kernel variable bootdev as ... machdep.guessed_bootdev, and add code to sysctl to parse its value and give a (not necessarily correct) name to the device we booted from (the main motivation for this code is to use the info in the PicoBSD boot scripts, and the impact on the kernel is minimal). NOTE: the information available in bootdev is not always reliable, so you should not trust it too much. The parsing code is the same as in boot2.c, and cannot cover all cases -- as it is, it seems to work fine with floppies and IDE disks recognised by the BIOS. It _should_ work as well with SCSI disks recognised by the BIOS. Booting from a CDROM in floppy emulation will return /dev/fd0 (because this is what the BIOS tells us). Booting off the network (e.g. with etherboot) leaves bootdev unset so the value will be printed as "invalid (0xffffffff)". Finally, this feature might go away at some point, hopefully when we have a more reliable way to get the same information. MFC-after: 5 days		2002-03-10 20:08:44 +00:00
