proot exits with proot: ./path/path.c:547: compare_paths2: Assertion `length2 > 0' failed

[nilsrennebarth]

Steps to Reproduce the Problem

1. Create a standard debian bookworm rootfs
2. Enter the rootfs via proot by proot -0 -r OUT/ROOT -w / -b /proc/ -b /etc/resolv.conf -b /etc/hosts -b /dev/ /bin/bash
3. Run the command systemd-tmpfiles --create debian.conf

Specifications

• Proot/Care version: 5.4.0
• Kernel version: Ubuntu 5.15.0-76-generic
• Host distribution: debian bookworm
• Guest distribution: debian bookworm

Remarks

I tried editing the debian.conf file, and found that entries starting with an L provoke the assertion failure. According to the manpage this should just create a symlink if it does not exist yet. Creating the same links by /usr/bin/ln works however.

What I tried is to to install various packages, among them systemd in a proot made chroot, and the systemd postinst failed with the said assertion failure.
