Add shared memory support to Proot

[JanuszChmiel]

May be, that this issue have been created previously. What do you think about adding shared memory support directly to Proot? Currently there is no easy technique, which would allow Termux Proot users to add this shared memory supported to various Linux distributions, which are being executed by Proot.
Namely, the following could be implemented to work.
(shmget, shmat, shmdt and shmctl)
Original library for Termux which solves this is available here:

Sure, I Am ready to intensively test and if working on my phone remotely will be required, no problem, I will ive you access by using tmate SSH client.
What do you think. Would be too complex to achieve this goal? If it would be too complex to create it for many Linux distributions, would be possible to create this support for Debian Buster ARM 64 Bit?
Thank you very much for yours analysis and for yours thinkink about my plea.

Hello, @JanuszChmiel !
Now proot supports shm, you can use shm via adding --sysvipc flag, when starting proot.

Thank you very much for yours complex programmers work. It had to be difficult. Do you think, that thanks to yours Proot extension to support shared memory, Pcmanfm and GTK3 library will finally stop do display warning shmget function not implemented?

Thanks to yours Proot extension, it is next very important Linux distribution support miracle. Because there are some Linux apps which really dependent on shared memory support. I will test it on some simple Linux distribution install script, where /dev/shm is not created to avoid some conflicts between various shared memory support approaches. Very well done and thank you, that you have used yours perfect programmers knowledge.

Here is The command result. [root20:36sbin]$ um x86_64 BUt ping binary do not exist on The installation. SO I do not know how to test if Internet functioning or no. When i Execute [root20:38sbin]$ pacman -Syu :: Synchronizing package databases... error: failed to update core (no servers configured for repository) error: failed to update extra (no servers configured for repository) error: failed to update community (no servers configured for repository) error: failed to synchronize all databases [root20:38sbin]$ It seems to Me, that there is some hydden problem. That there is complex way to go to configure foreign architecture so professionally like yours script allready do for normal situation when user install Archlinux and Proot is being used for Qemu. The complex issue is to find links for repositories and how to digitally sign some keys. But I will be patiently testing and I AM looking forward to The times, when pacman SYu will update whole distro and I will be even able to install Orca and Mate when using ArchLinux by using Qemu and Proot.

Then configure a mirror. It is not being set.

Look for files /etc/pacman.conf and /etc/pacman.d/mirrorlist.
