problem running on android twrp/adb shell

[99degree]

Dear all,

I am an Android system hobbyist and is a bit new to linux. I success to compile a arm64 kernel for a unlocked phone thus is running TWRP now. since the phone is old enough, the boot loader is not support for newer Android so I would like to seek for a way to bootstrap into Android 8/9 GSI into a container with twrp shell. I found that MINC is very interesting such that i might not need to do futher cross-compile LXC on arm64 anymore.

Here is what i did below in adb shell, apparently not working at all. Detail is in bottom, below is the pin-point message.

/usr/local/bin # ./minc -D -r /system_root --user 0:0 --usedev --pivot
mkdir: can't create directory '/tmp/minc4504-AmHQeg/root/etc': No such file or directory

Is there anybody found it interesting and offer some help?

Thanks

    BusyBox is a multi-call binary that combines many common Unix
    utilities into a single executable.  The shell in this build
    is configured to run built-in utilities without $PATH search.
    You don't need to install a link to busybox for each utility.
    To run external program, use full path (/sbin/ip instead of ip).
