From within the container it will still look like /home/chronos/user, but it is actually linked to /usr/local/home. Check if files/dirs appeared inside it:
ls -a /usr/local/home
If yes, then it works as intended. PlayOnLinux will still complain about noexec on /home, but this shouldn't be an issue since the real HOME is on /usr/local now.

bash: ./conty_lite_lz4.sh: /usr/bin/env: bad interpreter: Text file busy
Probably some process(es) is accessing it for writing (which is weird and shouldn't happen). If you have lsof installed, you can list all processes that are using the script with this command:
sudo lsof /usr/local/conty_lite_lz4.sh
And regarding playonlinux, i see it uses perl binary from /usr/local/bin, even though the builtin /usr/bin has a higher priority. What if you try to run it like this?
SUDO_MOUNT=1 USE_SYS_UTILS=1 ./conty_lite_lz4.sh --tmpfs /usr/local playonlinux
or
SUDO_MOUNT=1 USE_SYS_UTILS=1 ./conty_lite_lz4.sh --setenv PATH "/bin:/sbin" playonlinux
Also, does the internet connection work in other apps (in Steam or in Lutris, for example, or with simple ping)?
[FS_Check] Warning: The following file is located on a noexec mounted filesystem.
And i see PlayOnLinux complains about $HOME mounted with noexec.

$HOME is mounted on ChromeOS as noexec.
chronos@localhost /usr/local $ sudo lsof /usr/local/conty_lite_lz4.sh
chronos@localhost /usr/local $
chronos@localhost /usr/local $ SUDO_MOUNT=1 USE_SYS_UTILS=1 ./conty_lite_lz4.sh --tmpfs /usr/local playonlinux
bash: ./conty_lite_lz4.sh: /usr/bin/env: bad interpreter: Text file busy
chronos@localhost /usr/local $ SUDO_MOUNT=1 USE_SYS_UTILS=1 ./conty_lite_lz4.sh --setenv PATH "/bin:/sbin" playonlinux
bash: ./conty_lite_lz4.sh: /usr/bin/env: bad interpreter: Text file busy
Haven't tried a network connection in steam or lutris, which both error out.
in playonlinux, it looks like it is downloading, but then complains about a network error afterwards.

I do see these errors in dmesg:

Ok, i figured out the reason why this happens - this happens when the previously launched Conty wasn't unmounted. Perhaps you missed the moment when it asked to enter sudo password to unmount the image (assuming you don't have NOPASSWD set for umount) or it was roughly terminated.
mount | grep conty
I will fix this by mounting the image as read-only, so even if it's not unmounted you'll stil be able to run Conty as many times as you want.
For now you can either unmount the image manually or try to run Conty directly with bash to avoid this error:
SUDO_MOUNT=1 USE_SYS_UTILS=1 bash conty_lite_lz4.sh ls
Regarding internet connection, I guess the easiest way to check if it works is with ping or with wget (if ping doesn't work):
SUDO_MOUNT=1 USE_SYS_UTILS=1 ./conty_lite_lz4.sh ping 8.8.8.8
SUDO_MOUNT=1 USE_SYS_UTILS=1 ./conty_lite_lz4.sh ping google.com
SUDO_MOUNT=1 USE_SYS_UTILS=1 ./conty_lite_lz4.sh wget "https://www.google.com/"
/etc/resolv.conf and /etc/hosts get automatically binded to the container, so the connection should work, but maybe there are some other files need to be binded, i'm not familiar with ChromeOS file structure. You can try to bind whole /etc to the container (with BIND="/etc" env variable) and see if this helps.
And i still suggest to try to launch PoL in one of these ways and see if it changes anything (not regarding the "Text file busy" error but regarding the PoL itself and internet connection).
SUDO_MOUNT=1 USE_SYS_UTILS=1 ./conty_lite_lz4.sh --tmpfs /usr/local playonlinux
SUDO_MOUNT=1 USE_SYS_UTILS=1 ./conty_lite_lz4.sh --setenv PATH "/bin:/sbin" playonlinux

Yup. Definitely looks like it never unmounted properly.

Using regular mount command (sudo mount) instead of squashfuse

Re: network issues I see this:

We had to put a wrapper on ping to make that work for us:
#!/bin/bash
sudo -E /usr/local/sbin/capsh --caps="cap_net_raw+eip cap_setpcap,cap_setuid,cap_setgid+ep" \
--keep=1 --user=nobody --addamb=cap_net_raw -- \
-c "/usr/local/bin/ping.elf $@"
SUDO_MOUNT=1 USE_SYS_UTILS=1 ./conty_lite_lz4.sh ssh host works fine though.
Re: Playonlinux I see this:

Looks like an install starts right:

Looks like it gets stuck there.

(Maybe a force unmount might be an option if there's an error with mounting? Or just using the existing loopback device if it exists?

Maybe remapping home dir away from a noexec mount if it is detected as such might also be useful.

You can try to set custom HOME directory like this:
SANDBOX=1 HOME_DIR="/usr/local/some_custom_dir" SUDO_MOUNT=1 USE_SYS_UTILS=1 ./conty_lite_lz4.sh playonlinux
Or
SUDO_MOUNT=1 USE_SYS_UTILS=1 ./conty_lite_lz4.sh --bind /usr/local/some_custom_dir $HOME playonlinux
(Maybe a force unmount might be an option if there's an error with mounting? Or just using the existing loopback device if it exists?
As for unmounting when SUDO_MOUNT is enabled, i will try to find a solution.

I added a fix for the unmount issue, the script will use the same mountpoint now if possible. Could you please try the new squashfs-start.sh script? You can easily create new Conty from the existing conty_lite_lz4.sh like this:
First copy the squashfs image from the conty_lite_lz4.sh file (no need to rebuild it, just copy with dd):
dd if=/usr/local/conty_lite_lz4.sh of=/usr/local/image.squashfs bs=1272792 skip=1
Where bs=1272792 is the offset (can be viewed with ./conty_lite_lz4.sh -o)
After that download utils.tar and new squashfs-start.sh directly from this repo:
cd /usr/local
wget https://raw.githubusercontent.com/Kron4ek/Conty/master/squashfs-start.sh
wget https://github.com/Kron4ek/Conty/raw/master/utils.tar
Then just combine all these with cat:
cat squashfs-start.sh utils.tar image.squashfs > conty_lite_lz4_new.sh
chmod +x conty_lite_lz4_new.sh
from conty.

The squashfs-start.sh script appears to work.
changing $HOME does not though...
chronos@localhost /usr/local $ mkdir home
chronos@localhost /usr/local $ SUDO_MOUNT=1 USE_SYS_UTILS=1 ./conty_lite_lz4.sh --bind /usr/local/home $HOME playonlinux

Yep, it works as intended then.
But does PlayOnLinux work fine with HOME on /usr/local/home or still gets stuck at some point?
