That is due to shell scripting gotcha, see for example https://github.com/koalaman/shellcheck/wiki/SC2089

The real problem is $(uname -v)
It will output:#1 SMP PREEMPT Thu Aug 4 21:24:09 CST 2022
And PRoot will think the SMP is a program and PREEEMPT… is the program's arg.
Now i replace $(uname -a) with WHAT:

umm…
i think i resolve it…

umm…
nope
Once i run mv debian-test debian-backup
And this line doesn't work anymore

(you can see the hostname isn't your-hostname)

This is because this parameter wasn't even passed to proot

Seems that passing multiple arguments where some contains spaces through variable is difficult in base, inline proot invocation and -k "..." argument away from variable into exec line

So i changed the last line to:$proot -k\ "\Linux\dontknow-pad\5.19.2-aarch64\$(uname -v)\aarch64\localdomain\-1\" $command /usr/bin/login $@
PS:$proot=$PREFIX/bin/proot
