Subject: [PATCH 1/2] Do not limit swap to 128 GiB
|
|
|
667f11 |
|
|
|
667f11 |
The limit was part of change to limit suggested swap size in
|
|
|
667f11 |
kickstart which doesn't use the SwapSpace._max_size so there is no
|
|
|
667f11 |
reason to limit this for manual installations.
|
|
|
667f11 |
16 TiB seems to be max usable swap size based on mkswap code.
|
|
|
