| http://people.freebsd.org/~bsd/cdroot/ Ok. I've tried this route and it seems to be working, thank you all so much for your help and pointers. During burning the iso image, I get a message to my console, PREVENT_ALLOW - ILLEGAL REQUEST asc=64 ascq=0 error=04 this occurs as burncd is "fixing". However, I did reboot and it seems to work. I don't know how to get a trace-file of the bootup... but here are some things that I am a wee bit concerned about. I seemed to have one error that popped up that I don't know how to resolve, here is it "re-typed"... acd0: CD-RW <...> Mouning from root iso9660:cd0a no such device 'cd' setrootbyname failed iso_mountroot: can't find rootvp Root mount failed: 6 Mounting root from iso9660:acd0 I also see a few drives complaining (like the mouse), I think I know how to re-do the kernel to leave out the mouse driver though. Is this a cd driver that needs to be removed? Anyway, I log-in and everything works nicely. Cool. Given that I've gotten this far with cdroot, I think I'm going to stick with this solution... and figure out how it works. This kit makes three mfs for me: tmp, var, etc, dev. I'm wondering if the etc and dev must be done as mfs? My next step is to make a custom boot process: 1. Check to see if /dev/ad0s1b exists and is a swap partition, if so, load it. 2. Check to see if /dev/ad0s1? exists and is a FreeBSD partition. If so, see if it looks like a /tmp, /var, or /home partition. If so mount as appropriate. 3. Modify (2) above, to search on /ad?s1? for a similar structure. If so, then mount it using vinum. If steps 1-3 above fail, then assume it is an "uninitialized" box. Ask the user to verify this fact, and then create the partitions automagically. If there are two disks, ask the user if a software mirror is to be used, if so, then configure this as well. If any of you have any suggestions/comments/ideas as to how to best do this, I'd love to hear them! Best, Clark Thank you all so much for your suggestions and thoughts! My next step is to examine the file system: (a) if the "data" partition exists, then this can be mounted and /var and /tmp can be To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
