CBSD Base UpgradeMon 18 November 2019
Upgrade in CBSD means the same as in FreeBSD: increse only in patch version.
cbsd baseupdate service cbsd restart
For upgrade you need to stop the jail, set it to new base and start the jail.
cbsd jstop nginx cbsd jset jname=nginx ver=12.1 cbsd jstart nginx
CBSD will ask you how do you want new base files to be fetched, and default is
to download them. Other options include compiling from code and using host
system files as new base. If you upgrade more then one jail, the first
jstart will create base jail for the rest to use.
Once you've upgraded all your jails, it's time to cleanup
cbsd removebase ver=12.0
