Complicated installation

Installing rustic is not the most trivial task.

3. And even cargo install is not the most trivial for those who have not touched rust. At the beginning I did this

dnf install cargo
cargo install rustic-rs
    Updating crates.io index
  Installing rustic-rs v0.6.0
error: failed to compile `rustic-rs v0.6.0`, intermediate artifacts can be found at `/tmp/cargo-installLmGHaW`

Caused by:
  package `clap_builder v4.4.7` cannot be built because it requires rustc 1.70.0 or newer, while the currently active rustc version is 1.66.1

Yes, of course, I spent a some time getting more recent versions of cargo and was able to install using the third method, but it is too complicated compared to restic.

Thanks for opening this issue!

About 1): did you try the musl Versions? Those should work without glibc requirements. But have a look at the nightly builds!

About 2): I think this should be fixed by #919 in the next release.

Thanks, I just checked musl - at first glance it works.
I also tried using self-update on it - is this how it should be?

./rustic self-update
