Archlinux 打包 Linux kernel 中特定 module 的 package

繼半手動編譯 funUV dvb dongle USB電視棒 Linux modules後，

搞定打包Archlinux package 檔案的 PKGBUILD

以後只要以

#uname -a

查 linux kernel 的版本，

配合替換目標版本 linux PKGBUILD 檔中 checksum

https://gitlab.archlinux.org/archlinux/packaging/packages/linux/-/commits/main

就能完成FunUV dvb dongle 的 archlinux package。

 

如果 uname -a 是

Linux Arch64rexctUEFI 6.10.9-arch1-2

修改

pkgver=6.10.9.arch1

pkgrel=2

sha256sums=(...) 和 b2sums=(...) 前4行都替換成 linux 的 PKGBUILD 內容。
