[Bug 275295] Linuxulator: faccessat2 unsupported flag 0x100

            Bug ID: 275295
           Summary: Linuxulator: faccessat2 unsupported flag 0x100
           Product: Base System
           Version: 14.0-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: kenrap@kennethraplee.com

Recently a weird file permission issue had popped up with using the Brave
browser through the Linuxulator when trying to run it:

/usr/local/bin/linux-brave: /compat/ubuntu/opt/brave.com/brave/brave-wrapper:
Permission denied

The permissions were fine and the problem continued to persist after trying
multiple Ubuntu-lator re-installations, even with different versions, e.g.:
jammy, lunar, mantic.

Eventually I thought to peak into the dmesg output and found the following:

With regards to the "(gpg-agent)" line, I would like to note that I've also
been having `apt update` GPG errors in the Ubuntu linuxulation. I've used `deb
[trusted=yes] ...` in /compat/ubuntu/etc/apt/sources.list as a workaround to
get updates but users shouldn't have to do this either.
