Please fix the typo in pkgver.

Hello! I get this, I try to use rustup and set rustup default nightly , but this is of no use ``==> Extracting sources... -> Extracting KernelSU-1.0.5.tar.gz with bsdtar ==> Starting prepare()... error: failed to parse manifest at/home/xuanran/.cache/paru/clone/ksud/src/KernelSU-1.0.5/userspace/ksud/Cargo.toml`

Caused by: feature edition2024 is required

The package requires the Cargo feature called edition2024, but that feature is not stabilized in this version of Cargo (1.83.0 (5ffbef321 2024-10-29)). Consider trying a newer version of Cargo (this may require the nightly release). See https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#edition-2024 for more information about the status of this feature. ==> ERROR: A failure occurred in prepare(). Aborting... error: failed to build 'ksud-1.0.5-1': error: packages failed to build: ksud-1.0.5-1```

Right, I changed all of export RUSTUP_TOOLCHAIN= to nightly solve it

sorry, just update toolchain will solve it

@nyaruta Thank you for your feedback and suggestions!

I've discovered that the error with LTO occurs only when the build.rs linking functionality is not used. Please try the following patch:

diff --git a/userspace/ksud/build.rs b/userspace/ksud/build.rs
index 021418ac..8a16bff8 100644
--- a/userspace/ksud/build.rs

     let (code, name) = match get_git_version() {
         Ok((code, name)) => (code, name),
         Err(_) => {

This patch should resolve the LTO linking issue. If it works, I will update the PKGBUILD accordingly. Additionally, if we are not fetching our own magiskboot, we can remove the unzip makedepends.

Here is my PKGBUILD
