            Bug ID: 273414
           Summary: linuxulator regression in symlinks under zfs
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: freebsd@darkain.com

This commit broke symlinks when using Linuxulator:
https://reviews.freebsd.org/D40090

Further information can be found in:
https://reviews.freebsd.org/D40479

Repro steps, tested with latest 14.0-ALPHA3 ISO fresh install:

sysrc linux_enable="YES"
service linux start
pkg install fontconfig linux-c7-fontconfig font-adobe-75dpi

This command completes correctly:
fc-list

This command errors out:
/compat/linux/usr/bin/fc-list


After further testing, it was found that this issue only happens with ZFS file
systems. UFS file systems are unaffected by this issue.

The initial issue was discovered because due to fontconfig no longer being able
to see its own config file, Linux apps no longer had font rendering support.
The small test above is a smaller test case without requiring a full desktop
installation to see the issue.

A full video recording of the repro was also produced:
