That looks like what I need. I've got a seperate 32GB array to boot off of, so that's perfect. Now to just read some man pages.

Hmm...didn't think of that...didn't think fsck used that much RAM...and thought it was independent of the file system size. Right now it's got 2GB.

Re: Large file system creation
On our older servers that wouldn't even recognize a 2TB partition (which is where the OS was too), we used a CF card and CF card adapter to boot from. Slightly more gracious... CD/DVD drive isn't bad too. anyway - you don't change kernel every day. or pendrive. possibly floppy but i don't know if kernel (with at least disk driver and ufs) can fit on it compressed. i don't think so. ZIPdrives internal (i've got a bit for free). netboot or simply small hard disk. there are lot of options. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
