Comment 3 for bug 840333

There is a relevant bug report against logrotate: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=656060

I generally agree with the bug, but in practice u-u's logs compress well and in compressed form take one block:

$ du -sh /var/log/unattended-upgrades/*
16K /var/log/unattended-upgrades/unattended-upgrades-dpkg.log
4.0K /var/log/unattended-upgrades/unattended-upgrades-dpkg.log.1.gz
4.0K /var/log/unattended-upgrades/unattended-upgrades-dpkg.log.2.gz
4.0K /var/log/unattended-upgrades/unattended-upgrades-dpkg.log.3.gz
4.0K /var/log/unattended-upgrades/unattended-upgrades-dpkg.log.4.gz
4.0K /var/log/unattended-upgrades/unattended-upgrades-dpkg.log.5.gz
4.0K /var/log/unattended-upgrades/unattended-upgrades-dpkg.log.6.gz
0 /var/log/unattended-upgrades/unattended-upgrades-shutdown.log
4.0K /var/log/unattended-upgrades/unattended-upgrades-shutdown.log.1.gz
4.0K /var/log/unattended-upgrades/unattended-upgrades-shutdown.log.2.gz
24K /var/log/unattended-upgrades/unattended-upgrades.log
4.0K /var/log/unattended-upgrades/unattended-upgrades.log.1.gz
4.0K /var/log/unattended-upgrades/unattended-upgrades.log.2.gz
4.0K /var/log/unattended-upgrades/unattended-upgrades.log.3.gz
4.0K /var/log/unattended-upgrades/unattended-upgrades.log.4.gz
4.0K /var/log/unattended-upgrades/unattended-upgrades.log.5.gz
4.0K /var/log/unattended-upgrades/unattended-upgrades.log.6.gz

If logrotate switches to detect the need for compression automatically, I will stop overriding that in the package.
