If you don't want to create a designated swap partition (e.g. if you plan to downsize it later) and don't want to play
|
||
|
|
around with *GPartEd*, you can create a swap**file** instead.
|
||
|
|
|
||
|
|
To create a 512 MiB swapfile, do the following:
|
||
|
|
|
||
|
|
dd if=/dev/zero of=/swapfile bs=1024K count=512
|
||
|
|
mkswap /swapfile
|
||
|
|
swapon /swapfile
|
||
|
|
|
||
|
|
To automatically add the swapfile upon boot, add this line to the `/etc/fstab`:
|
||
|
|
|
||
|
|
/swapfile swap swap defaults 0 0
|
||
|
|
|
||
|
|
|
||
|
|
You can later easily change the size of the swapfile by re-creating a smaller or larger one.
|
||
|
|
|
||
|
|
You only have to make sure the file is contiguous or `swapon` might give an error.
