debian系统永久关闭swap方法

从下面可以看出GPT UEFI模式的还有dev-sda3.swap loaded inactive dead Swap Partition，需要关闭dev-sda3

root@debian:~# systemctl --type swap --all
UNIT          LOAD   ACTIVE   SUB  DESCRIPTION
dev-sda3.swap loaded inactive dead Swap Partition

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

1 loaded units listed.
To show all installed unit files use 'systemctl list-unit-files'.

使用如下方式可以永久关闭

root@debian:~# systemctl mask dev-sda3.swap
Created symlink /etc/systemd/system/dev-sda3.swap → /dev/null.
