pcre2 library is not in Ubuntu Main, and therefore cannot be used, at runtime, by such a core package as systemd.

once pcre2 is available in main, and thus has full Ubuntu Security support, I will be able to enable pattern matching support.

+ Journalctl compiled without pattern matching support, pcre2 is not in

Maybe we can have `journalctl-grep` package for administrators that use this grep functionality for checking what happened? Nowadays debugging is recognized as foremost computing activity, even chips have special JTAG pins to allow online debugging.

I could expect most of the system administrators with big logs would appreciate faster searching of log files thanks to `journalctl -g` in the leading cloud operating system.

journactl --grep works in Ubuntu 19.10 (but not 19.04 or older versions).
