While you are there, in either method, you can also shorten the boot delay time from the default 10 seconds to (say) 3 seconds. Noted.

Sorry, I forgot to mention that altering the /boot/grub/menu.lst to display less kernels than the default All only takes effect after the next kernel update. Making any changes in the StartUp-Manager I thought to become effective immediately.

Re: New partition
Hi Simon, Have you installed the drive yet? Specifically, what device does it come up as? To list available disks, use.. # fdisk -l It should be something like /dev/sdb The steps to setup what you're after are: 0. Partition new drive (fdisk /dev/sdb) 1. Format new drive (mke2fs) 1a. Adjust filesystem parameters (tune2fs) 2. Mount drive in a temporary location (/mnt/sdb1) 3. Copy /home (tar cf - -C /home . | tar xpf - -C /mnt/sdb1) 4. Remount disk at /home (umount /mnt/sdb1; mount /dev/sdb1 /home) 5. Make mounting automatic.. edit '/etc/fstab' A couple of tips: - Enable root logins before testing. (Add a root password) - When happy, login as root, unmount /home and delete any of the unwanted data in the mow hidden /home When you're happy that you've done everything correctly, you can disable root logins. Ann alternative, which I feel works better.. skip step 4, and remount the new disk at /users, (or some other new location) then edit /etc/password to make the users's home directory to be '/users/username' rather than '/home/username'. This has the benefit of keeping everything accessible, and obvious, particularly is anything should go wrong.

I'd start by logging in as root (naughty on Ubuntu perhaps, but means your not accessing files in your users ~ while doing all this stuff). Have you installed the drive yet? Specifically, what device does it come up as? To list available disks, use.. # fdisk -l It should be something like /dev/sdb The steps to setup what you're after are: 0. Partition new drive (fdisk /dev/sdb) This is optional for most operations (Linux can read the device raw), but required if you want to access the data from another OS. 1. Format new drive (mke2fs) I'd go with `mkfs.ext3` 1a. Adjust filesystem parameters (tune2fs) I usually skip this (but if you need special setups you'll want to do it) 2. Mount drive in a temporary location (/mnt/sdb1) 3. Copy /home (tar cf - -C /home . | tar xpf - -C /mnt/sdb1) `rsync -av /home/* /mnt/sdb1` would be another option 4. Remount disk at /home (umount /mnt/sdb1; mount /dev/sdb1 /home) Before doing this you might want to consider removing all the data currently in /home/ If you leave it all there, you gain no space on your existing filesystem from adding the new drive. 5. Make mounting automatic.. edit '/etc/fstab' A couple of tips: - Enable root logins before testing. (Add a root password) You can boot into root without a password from GRUB iirc. - When happy, login as root, unmount /home and delete any of the unwanted data in the mow hidden /home I do this further up, but this is probably safer. When you're happy that you've done everything correctly, you can disable root logins. Ann alternative, which I feel works better.. skip step 4, and remount the new disk at /users, (or some other new location) then edit /etc/password to make the users's home directory to be '/users/username' rather than '/home/username'. IMHO, for a single (or even multi user) desktop, changing /home/ makes more sense then fiddling the configs like this. kk This has the benefit of keeping everything accessible, and obvious, particularly is anything should go wrong.
