_netdev? No, I have added it now and will have to see what happens
next time I reboot.
Is that even required when the fstype is NFS? Who would mount a file system
via NFS when the file system is a local one, and what would _netdev do if
someone did that? What does the option do when remounting a file system
(mount -o remount)?
In any case, once I am or was logged in as a user, /home can not be
unmounted. How would suspending to RAM deal with that?

Does this mean I need as much swap space as I have RAM on a physical disk?
I'm using SSDs for everything but /home, and SSDs are way too expensive for more
than the system and a small amount of swap space.
I thought suspending to RAM means to suspend to RAM and _not_ to disk, so it
won't need that much swap space. If it requires as much swap as RAM, the feature
is totally useless.
