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. ** Bug watch added: Debian Bug tracker #656060 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=656060 ** Changed in: unattended-upgrades (Ubuntu) Status: New => Confirmed ** Changed in: unattended-upgrades (Ubuntu) Status: Confirmed => Opinion ** Changed in: unattended-upgrades (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unattended-upgrades in Ubuntu. https://bugs.launchpad.net/bugs/840333 Title: /etc/logrotate.d/unattended-upgrades should not have compress option Status in unattended-upgrades package in Ubuntu: Opinion Bug description: I think that log files compression lowers the system performance on desktop computers which have now enough disk space for storing old logs. The "nocompress" and "compress" options of logrotate configure 2 different behaviours of logrotate. If the log file isn't compressed, logrotate will just rename it to something like 'log_file_name.log.1' with quite no disk input/output. If the log file is compressed, logrotate will read the file, compress it and rewrite the content into a new file with a name like 'log_file_name.log.1.gz'. I think that files compression is a good tradeoff only in case the compressed files have a longer lifetime than the log files (i. e. man pages, documentation, fonts, Debian package files, ...). Drawbacks of log files compression : - increases disk input/output - increases cpu and memory usage - increases energy consumption - slightly decreases the disk lifetime ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: unattended-upgrades 0.72.1ubuntu1 ProcVersionSignature: Ubuntu 2.6.38-11.48-generic 2.6.38.8 Uname: Linux 2.6.38-11-generic x86_64 Architecture: amd64 Date: Sat Sep 3 15:16:34 2011 InstallationMedia: Lubuntu 11.04 "Natty Narwhal" - Release amd64 (20110427) PackageArchitecture: all ProcEnviron: LANG=fr_FR.UTF-8 SHELL=/bin/bash SourcePackage: unattended-upgrades UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unattended-upgrades/+bug/840333/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
