Thanks to @stefanoStefano Marinelli 's excellent article about syncing Time Machin with a FreeBSD jail, I decided to give it a try, and since the instructions were clear and easy, I didn't expect much trouble.

I bootstrapped 15.0-RELEASE, ran doas bastille create -V tmjail 15.0-RELEASE 192.168.xx.xx/24 igc0

System said Attempting to create jail: tmjail
Valid IP.......
Creating a thinjail....

But then: jail: tmjail: exec jib: No such file or directory, Failed to create jail....

I tried it several times, I checked that jib is in my path, I ran it as root. I deinstalled Bastille, deleted all directories and ZFS datasets, reinstalled everything but the error is still there.

It seems like the script does not find jib although it's in the path.

Do you have any ideas? I am quite sure that I didn't have this issue before I upgraded to 15.
