i'm also pretty ignorant about these details, but wouldn't that make it
hard to find/match the debugging symbols?  aiui, the build-id is used by
gdb to find the symbols for debugging.  for example:

0 dkg at alice:~$ file $(which notmuch) 
/usr/bin/notmuch: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=ef8fab73e1088840f0c5abe7dcbdc5a1246272cd, stripped
0 dkg at alice:~$ dpkg -L notmuch-dbgsym | grep build-id.*debug$
0 dkg at alice:~$ 

does this mean that galera-3 debugging symbols won't be easily findable?

then again, the debugging symbols for galera-3 look like they're being
generated in a way that is pretty out-of-date, and hasn't been touched
in at least 3 years, so maybe the maintainers don't care about these
symbols very much:


just my 2¢,
