chore(scripts/setup-ubuntu): retarget symbolic link to prepare for aosp-libs package

[robertkirkman]

• Dependency of bionic-host: rename to aosp-libs, bump to 9.0.0-r76, add aosp-utils subpackage, revbump revdeps #22906

[Grimler91]

Please add both symlinks, and then we can remove the old one after the bionic-host PR has been merged. This way bionic-host/aosp-libs is buildable even in the transition period

I am sorry for the inaccurate title, technically, using exact terminology, this is "retargeting" not "renaming" the symbolic link,
the "name" has to remain "/system" the entire time, and, what you suggested is a good idea, I wish I knew a way to do that, but I am not sure if that is possible.
Do you know if there is a way to implement what you are describing, a symbolic link that can target two different folders at the same time?

I could try to use something like this, but I think this probably wouldn't work, I will still test this, if this is what you mean:

$SUDO ln -sf /data/data/com.termux/files/usr/opt/bionic-host /system
$SUDO ln -sf /data/data/com.termux/files/usr/opt/aosp /data/data/com.termux/files/usr/opt/bionic-host

I tried those commands, and unfortunately, doing that does cause this error

mkdir: cannot create directory ‘/data/data/com.termux/files/usr/opt/bionic-host’: File exists

at this line of the current bionic-host package.

termux-packages/packages/bionic-host/build.sh

Line 102 in 59355b9

mkdir -p "${TERMUX_PREFIX}/opt/bionic-host/usr/icu"

I'll think about this problem for a while and try to find out if there is any kind of solution that meets the continuous uptime requirements.

[Grimler91]

Ah, right, sorry, I read to fast and thought the symlinks were the other way around. Nevermind! Let's get this in, should be pretty safe since only bionic-host is affected..

[Grimler91]

Thanks!
