Resize Linux Partition
===========================
Archive from Pastebin. On my old Arch Linux laptop, I resized 
the partition twice, both to mess with the size of my Windows 
partition when I was dual booting at the time.

- Boot into Arch installation medium.
- Delete and remake the partition you want to replace, make sure 
  the start header is where you want. (fdisk + mkfs.ext4)
- Make two folders in ``/mnt`` corresponding to the new filesystem 
  and the old one, then mount the partitions.
- Delete the lost+found folder from the new filesystem, then copy 
  EVERYTHING (``cp -p -r -v``) (p = permissions, r = recursive, 
  v = verbose). Leave the old filesystem alone for a little.
- Delete and regenerate fstab. Remember to turn on the swap 
  partition and mount the EFI partition. 
  (``genfstab -U /mnt > /mnt/etc/fstab``)
- GRUB install not needed, just remake the config 
  (``grub-mkconfig -o /boot/grub/grub.cfg``).
- GRUB config now pointing to new partition, reboot and make sure 
  it works.
- Using fdisk, make the new filesystem the size desired (START 
  MUST BE LEFT AS IS!). Delete any partitions not wanted (if swap 
  or EFI is modified remember to regenerate fstab). **SAY NO TO 
  REMOVING SIGNATURE!!!**
- After being modified, run ``e2fsck -f /dev/sdX``. Say no to 
  anything if prompted.
- ``resize2fs /dev/sdX``.
- To test it, mount the filesystem and chroot to make sure it 
  works.
