did anyone used this little thing? i have system like this: # /dev/ad0: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 18432000 0 4.2BSD 2048 16384 28552 (/) b: 2457600 18432000 swap c: 312581808 0 unused 0 0 d: 291692208 20889600 4.2BSD 2048 16384 43400 (/home) and would like to have one partition+swap, not two. after booting from CD and turning on shell will 1) copy files from partition a to d, and put files from partition d's root to d's home. mount -o async,noatime /dev/ad0d /mnt cd /mnt mkdir home mv * home mount -r /dev/ad0a /mnt2 (cd /mnt2;tar cf - .)|tar xpf - umount /mnt2 cd .. umount /mnt 2) bsdlabel and delete b, set up a partition to end of disk-1GB, and b after a, not deleting d (yes it will overlap temporarily) 3) dd if=/dev/ad0d of=/dev/ad0a bs=1m to move 4) bsdlabel and remove d 5) FINALLY - growfs /dev/ad0a 6) boot0cfg to make it all bootable. can i do 5) without fear? i want to do full dump of my data, but don't like to do it twice (before for sure, and then after repartitioning).
