Re: [gentoo-user] Moving root filesystem to a new partition
I bind mounted / then copied /dev to the new partition. This was advice given earlier, the first time it happened to me: I finally found an earlier replay to a similar request from me. All is now well. Thank you for the advice.

I usually move things file wise with cp then move things physically in the case as well. My OS is always on hda. The grub config is on hda1 and grub bootloader is on the MBR of hda as well. So, I don't have to edit grub on mine. I do boot once by using the edit feature of grub, just to make sure before I move things physically. You do have to plan these things tho. Wouldn't hurt to write down on paper where everything is and don't erase anything until you are sure your ducks are in a row. Maybe even write notes on the drive with a post it note. Dale :-) :-)
Re: [gentoo-user] Moving root filesystem to a new partition
Just restore your latest backup to the new partition, then edit /etc/fstab to specify the proper layout. Easy - I do it often. A good idea. If for some reason you don't have disk image backups...grab something like system rescue cd, and partimage the whole drive and the restore from it... ~daid

[gentoo-user] Moving root filesystem to a new partition
Can someone tell me what steps are necessary to move the / filesystem to a new partition? I recall someone helping me with this before, but cannot find the email.

I recall there are some other steps necessary. /dev needs at least the entries console and null, and tty1 for splash things (I think). You could create them like this: mknod c 5 1 /dev/console mknod c 1 3 /dev/null mknod c 4 1 /dev/tty1 Or copy over your original /dev directory (without the stuff udev added) from the old system: mount -o bind / /mnt cp -a /mnt/dev /newroot/ Wonko
