(I wanted to file a PR, I swear, but that day the FreeBSD-website was down and later I forgot...) The question has come-up in various lists and newsgroup the last couple of weeks. As IDE2SCSI RAIDs are getting increasingly cheap and big, this problem will show-up more often than not in the future. A howto for gpt would also be good. Not that I need one now, but now that 1GB mail-storage has come en vogue.... cheers, Rainer -- =================================================== ~ Rainer Duffner - rainer@ultra-secure.de ~ ~ Freising - Munich - Germany ~ ~ Unix - Linux - BSD - OpenSource - Security ~ ~ http://www.ultra-secure.de/~rainer/pubkey.pgp ~ ===================================================
