Hello Neil,
For running everything in FreeBSD Jail, if to use mtx-changer by bacula
user is needed sudo, I think the sudo needs to be added to ChangerCommand
too:
Autochanger {
Name = "TL2000"
Device = "HH-LTO7"
ChangerDevice = "/dev/pass1"
ChangerCommand = "sudo /etc/bacula/scripts/mtx-changer %c %o %S %a %d"
}
For Perl, it is used by mtx-changer script. I see in mtx-changer that the
Perl command can be changed to commented by default awk/sed/cut commands.
Inside mtx-changer after the Perl command is this comment:
# If perl isn't installed, you can use by those commands
Best regards,
Marcin Haba (gani)
