INN2 on a Raspberry Pi 4? | Migrating between instances of INN2

If you think adding native support for xz compression would be useful, 
the program could be searched for in m4/compress.m4 and, if you build 
INN with the --with-log-compress=xz flag, it would normally do the trick 
(not personally tested though).
Wouldn't it correspond to your local change? (if that's the case, such a 
change could easily be merged upstream, and usable for your needs as 
well as other people's needs)

BTW, I see that this --with-log-compress configure flag is not 
documented (it is only mentioned in the output of "./configure --help").
I'll mention it in the relevant manual pages (at least INSTALL, newslog, 
news.daily and scanlogs).  Current supported methods are gzip, bzip2, 
compress and cat (meaning no compression at all).


Also, if we want to be smarter, allowing to change the compression 
method at run-time could be useful, for instance by adding a 
compressformat keyword to news.daily, which would pass it to scanlogs.
It would even allow to pass options to improve the compression.  For 
instance with compressformat="gzip -9" to improve compression with gzip, 
or compressformat="xz --memlimit=50%" to limit the hog you mentioned.
