Will this work if any partitions on <device> are mounted? When I have run fdisk to modify a partition table, the kernel complains that it can't reread the partition table if there are mounted filesystems on the target disk. If the root filesystem is on the target disk, a reboot might be required. (In the past, fdisk has alerted the kernel if there's been a partition table change, so partprobe might not be needed.) And of course, have backups when messing with the partition table. :) --keith -- kkel...@speakeasy.net
