let's always first check if there is already a key in the keyring
available before we try to get the key from some more involved means.

We're still having issues with corrupted dumps when we try to dump only
the live part of btree nodes.

so since up until the last merged changes, this entire gh action pretty
much equated to a no-op, afaict. and even now, the only thing i added in
PR #272 is a formatter check only for *.nix files.
i plan to add more checks soon that will be run by `nix flake check`.
but as of right now, adding this is the quickest way to make sure at
least something useful is done by this workflow.

formatters (rustfmt, clang-format, ...). For full list see

it also provides a way for abstracting `system` and provides optional
modules, like treefmt-nix.

it shouldn't really be our job to define an overlay. it doesn't do
anything for us, afaict, and is trivial to implement for downstream
users of the flake if they so desire.
also the overlay doesn't even overlay anything, there is no package
called `bcachefs` in nixpkgs.

Only bkeys of the specified type will be printed.
Also, this reworks the error type in bch_bindgen to be able to
represent other kinds of error than just "invalid btree id".

If the user passes a single device node during the mount and
we have no information for it in the udev db, we read up the
super block. When we do this, if the FS only has 1 block device
we will simply go ahead and do the mount instead of walking
all the block devices and reading up super blocks looking for
devices with a matching FS UUID.

Introduce an env. variable for users that have a broken blkid which
renders the udev db as incomplete. Only checks for the existence
of the variable, not its value.

If the udev database contains information about bcachefs, utilize it.
Otherwise, resort to traversing block devices and checking for
bcachefs super blocks.
V2: Reduce number of places we call read_super_slient in interators

Add an environment variable that indicates we prefer to run bcachefs
code in the kernel, not userspace - this is for the test environment
where it's easier to debug kernel code.

It is more idiomatic to use `commands::mount` than
`commands::cmd_mount`.

Without the single char (with ':' if optarg expected) only the long
argument string would successfully parse.
For example, now "-lasdf" parses the same as "--label asdf"
We need to check when stdin has been closed - otherwise we'll spin
because select() will return immediately.
