Hi,

<znavko@tutanota.com> skribis:

> # guix system reconfigure /etc/config.scm
> ...
> guix system: error: exception caught while executing 'start' on service '=
swap-/dev/sda2':
> In procedure swapon: "/dev/sda2": Invalid argument...

According to swapon(2), there are 3 conditions that can lead to this
error:

       EINVAL The file path exists, but refers neither to a regular  file  =
nor  to  a
              block device;

       EINVAL (swapon())  The  indicated path does not contain a valid swap=
 signature
              or resides on an in-memory filesystem such as tmpfs(5).

       EINVAL (since Linux 3.4)
              (swapon()) An invalid flag value was specified in flags.

Did you run =E2=80=9Cmkswap /dev/sda2=E2=80=9D beforehand?

Thanks,
Ludo=E2=80=99.
