Would that means that you'll enable regex support in journald :)
That would made pcre2 pseudo-essential, note that the last essential
package to use pcre (version 1) is grep. Also, libpcre2 libraries are
located in /usr/lib and not /lib, debian is not supporting late mounting
/usr for a few releases but that still needs to be noted somewhere.
We also need to keep in mind that the compiled file context files will
not be architecture agnostic anymore, but libselinux should be smart
enough to ignore these files if their architecture is not matching (ie.
in multi-arch case). Unlike on RHEL/Fedora, these files are generated on
the machine instead of shipped in a (noarch/arch:all) package so I don't
think we need to change anything on how they are handled. (See:
https://janzarskyblog.wordpress.com/2017/09/06/why-we-dont-need-to-ship-file_contexts-bin-with-selinux-policy/).
So for me that should be fine.
I'll still try to do some benchmarking
