Re: Got tired of waiting for suspend/resume (something like that)

The OP described the use of an ephemeral key to encrypt the swap. Are
you familiar with that practice? If not, better acknowledge it and let
the conversation pass by you.

You completely misunderstood the problem. The swap is waited by initrd
for resume, but that is not wanted by the user. It is a bug of newer
versions of initramfs-tools that try to set up resume automatically and
do not detect ephemeral keys.

Indeed. On the other hand, LVM also allows to make a partition-like
system with labels.

These options have been introduced for some reason, they do not matter.
What matters is that a lot of people, when confronted with a problem,
will not take time and try to understand how it all fits together.
Instead, they will just take the first solution they think of, implement
it, find drawbacks, fix them the same way, entering an endless loop of
piling kludges over kludges. I know several people who function like
that.

The solution you quoted is a perfect example of that. Better learn to
recognize them rather than propagate them.
