stucked when adding path in WSL1

[skt041959]

I'm using z.lua with zsh in WSL1 with ArchWSL (https://github.com/yuk7/ArchWSL).
It stucked when adding path like /usr/sbin/lua /home/xxx/.zplug/repos/skywind3000/z.lua/z.lua --add /mnt/c/Users/xxx

Debugged with strace, it's calling endless file rename.

You have a broken lua, try a new lua or luajit instead.

The same issue here. All package has been updated except glibc: ignoring package upgrade (2.30-3 => 2.31-5).
lua -v gives the following output.

This is a bug of rename() system call in the latest WSL1 :

microsoft/WSL#5505

Before wsl team fix it, there is a work-around:

• update z.lua to the latest version
• install lua-filesystem

sudo apt-get install lua-filesystem

The latest z.lua will utilize lfs module to detect file existence.
