Either > that, or ask Robert for a bootsector that says the same thing... FWIW, there's existing i386 code to do this in newfs_msdos.c. Just change the message displayed. I can always oblige with a FAT filesystem bootstrap, if we want to use FAT floppies. Because of a lower metadata overhead, FAT could be a lot more space-efficient than UFS. We can lose 90% of UFS's 16K for boot + superblock, for instance. And FAT dirents are only 32 bytes. -- Robert Nordier To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
