InPlace upgrade RockyLinux8 to 9 - OK.
But:
After ugrade can not start openfortivpn - have permission error about ppp0 and " openfortivpn@cfg1.service: Failed with result ‘timeout’"
selinux - disabled… firewall - nftables.
In the systemd openfortivpn unit was:
[Service]
Type=notify
Now this and all ok :
[Service]
Type=simple <—modify
PrivateTmp=true
ExecStart=/usr/bin/openfortivpn -c /etc/openfortivpn/%I.conf
OOMScoreAdjust=-100
DeviceAllow=/dev/ppp rw <—add
DeviceAllow=/dev/null rw <—add
