When doing a fresh install with today's current MicroOS image (0505) and with
the MicroOS transactiona container pattern, installing additional packages
after the initial install fail. For example:

# transactional-update pkg install --download-in-advance firewalld
...
Additional rpm output:
/sbin/ldconfig: Warning: ignoring configuration file that cannot be opened:
/etc/ld.so.conf: Permission denied
/sbin/ldconfig: Can't create temporary cache file /etc/ld.so.cache.xeizJJ:
Permission
denied
warning: %post(libgirepository-1_0-1-1.68.0-1.2.x86_64) scriptlet failed, exit
status 1

There are multiple messages like this.

However, when I disable selinux by:

setenforce 0

The install succeeds.

Disabling selinux as a workaroud for installing a few additional packages to
the MicroOS container works as long as this is done manually. However, for
automated updates, one would have to permanently disable selinux, which I don't
thinks is a good idea.

Not sure if the following is related. During initial boot of the installed
systemd complains about the following role:

system_u_system_r_init_t
