When updating from vCSA 7.0 U3g or earlier, localos user "named" will be deleted.
From journalctl, we see that "named" was deleted just before erasing bindutils-XX.XX.XX-X.phX.x86_64

Due to a known issue in the bindutils packaged version with the vCSA, the named user/group is incorrectly deleted when uninstalling old bindutils.
This issue is fixed in vCenter Server 7.0 U3f (P05).
Workaround:
Log in to the vCSA shell and run the following command to manually create a named user/group:# groupadd -r named
# useradd -g named -d /var/lib/bind -s /bin/false -M -r named
# chown -R root:named /var/lib/bind
# chmod 0770 /var/lib/bind
There are no tasks using named, so it does not affect any services in vCenter.
