I have been writing a script to build a system from a mfsboot startup and it is going well but I want to revisit part of the script that I don't think I did a very good job with. Is there an automatic way to tell which of the devices shown in /dev is a likely system drive? This is before anything is mounted. We can usually figure it out ourselves, but is there a way for a script to figure out automatically which character device could be the one we are going to put the OS on and use as our boot drive? I know this sounds really obvious and you can tell scripts not to use /dev/acdx as they are CDROM devices, but system drives can actually take many different names depending on whether they are RAIDs SCSI IDE, etc. Any good suggestions are appreciated.
