Comment # 11 on bug 1186267 from Roy Bellingan

Very sorry but I am still suffering from this bug.
Tumbleweed installed from iso downloaded on 2021/10/07

If I run under strace I have

strace php-fpm 
...
openat(AT_FDCWD, "/etc/php8/fpm/php-fpm.conf", O_RDONLY) = -1 EACCES
(Permission denied)

ll /etc/php8/fpm/php-fpm.conf
-rwxrwxrwx 1 root root 5324 Oct  9 00:50 /etc/php8/fpm/php-fpm.conf

if I stop rcapparmor stop

Still same problem

But now the funny part!

cp /etc/php8/fpm/php-fpm.conf /tmp/miao

strace php-fpm --fpm-config /tmp/miao

openat(AT_FDCWD, "/tmp/miao", O_RDONLY) = -1 EACCES (Permission denied)

o.O

Of course if I put a wrong path 

openat(AT_FDCWD, "/tmp/miao2", O_RDONLY) = -1 ENOENT (No such file or
directory)

BTW I see that a few lines before it was able to open 
openat(AT_FDCWD, "/etc/php8/conf.d/zlib.ini", O_RDONLY) = 3
And the other config file

I will try later if I can to compile in local and see what it happens.
