--- Comment #1 from Kristyna Streitova ---
The problem is on the first row of the %post section, where '%service_add_post'
macro is called:
<snip>
%post
%service_add_post mysql.service mysql@.service mysql.target
mysql@default.service
</snip>
Besides other things, '%service_add_post' macro runs 'systemctl preset' for all
these four services. mysql@default.service (it's a symlink to mysql@.service)
causes the problem.
I tried it separately and it seems that 'systemctl start' works fine, but
'enable' or 'preset' cause the "Too many levels of symbolic links" error
message.
$ ls -la /usr/lib/systemd/system/*mysql*
lrwxrwxrwx 1 root root 14 Feb 11 18:37 mysql@default.service -> mysql@.service

@systemd maintainers: Could I ask if this is correct systemd behaviour? I
thought that since this commit [1] it's possible to enable/disable services via
symlinks in /usr. Thank you in advance for any hint.
