converter between `.zip` and `.tar.xz` bootstraps

[owokitty]

please provide a converter between .zip and .tar.xz bootstraps so they can be swapped to different types of Termux APKs. Thanks.

Maybe also support converting to and from libtermux-bootstrap.so format

Convert from .tar.xz to .zip

mkdir bootstrap
cd bootstrap
tar -xJf ../bootstrap-aarch64.tar.xz
while read -r -d '' link; do
echo "$(readlink "$link")←${link}" >> SYMLINKS.txt
rm -f "$link"
done < <(find . -type l -print0)
# option one
zip -r9 ../bootstrap-aarch64.zip ./*
# option two
sudo apt-get update
sudo apt-get install -y p7zip-full
7z a ../bootstrap-aarch64.zip ./* -mfb=258 -mpass=15

Convert from .zip to .tar.xz

mkdir bootstrap
cd bootstrap
unzip ../bootstrap-aarch64.zip
cat SYMLINKS.txt | awk -F "←" '{system("ln -s '"'"'"$1"'"'"' '"'"'"$2"'"'"'")}'
XZ_OPT=-e9 tar cJf ../bootstrap-aarch64.tar.xz ./*
