Hi,

we're having trouble with the old passenger-cagefs problem on CloudLinux 10.

OS: CloudLinux 10.2 / AlmaLinux 10.2 (Lavender Lion)
Plesk: 18.0.81
Passenger: 6.2.0.1

Passenger, Node.js and Ruby are installed (and have already been reinstalled).

We know this article:
https://support.plesk.com/hc/en-us/...-server-with-CloudLinux-OS-and-CageFS-enabled

Unfortunately, the passenger-cagefs package is no longer available for CloudLinux 10 / AlmaLinux 10.

It looks like Passenger creates temporary files in /tmp/passenger.spawn.*, but these files are not accessible from within CageFS.

We get errors like:

Cannot open /tmp/passenger.spawn.XXXX/envdump/user_info
Cannot open /tmp/passenger.spawn.XXXX/envdump/envvars
Cannot open .../args.json: No such file or directory
We also noticed that /etc/cagefs/cagefs.mp only contains /usr/share/passenger, and there doesn't seem to be any specific CageFS integration for Plesk's Passenger packages.

Before manually changing Passenger paths or CageFS mountpoints, we'd like to know if there's an official solution for CloudLinux 10.

Is this a known issue, or has anyone already found a working solution?

Thanks!
