Editing config.modules is fine; it's designed for that. Set "auto=no" in the line you are editing and it will be kept if the file is regenerated. pws ^ permalink raw reply [flat|nested] 8+ messages in thread

For completeness, however, as it says at the top of config.modules you may need to run "make prep" to regenerate the files needed.

I don't think this is actually necessary, because the "all" target has config.modules as a dependency and "make all" will run the same commands as "make prep". ^ permalink raw reply [flat|nested] 8+ messages in thread

Is there any > simple way to turn off the installation of these? Nice idea. I tried that with the Debian zsh package. Using the following sed oneliner helped to remove stuff very likely not needed on Debian: sed -e 's:Completion/\(AIX\|Darwin\|Solaris\|Cygwin\|Mandriva\|openSUSE\)/\*/\* ::g' -i config.modules But the gain in free disk space inside /usr/share/zsh was just about 5% as most of the disk space is needed for Completion/Unix. > Any other tips on shrinking installed size? I don't know, but depending on your installation it may help to just install the .zwc files and not the source and the .zwc files. As I have been told on IRC, it should suffice for running zsh to have the .zwc files instead of their source around. Then again, in my case the Unix.zwc is bigger than the Unix directory contents it's generated from, but I suspect a performance penalty if you just install the source instead of the .zwc files. :-) ncdu shows nice where the disk space is going to: --- /usr/share/zsh/functions/Completion -------------------------------- /.. 3.0MiB [ 33.9% ##########] Unix.zwc 2.3MiB [ 26.5% ####### ] /Unix 380.0KiB [ 4.2% # ] /Zsh 284.0KiB [ 3.1% ] /Base 256.0KiB [ 2.8% ] /Debian 252.0KiB [ 2.8% ] Base.zwc 248.0KiB [ 2.7% ] /X 244.0KiB [ 2.7% ] Linux.zwc 236.0KiB [ 2.6% ] Debian.zwc 220.0KiB [ 2.4% ] Zsh.zwc 212.0KiB [ 2.3% ] X.zwc 200.0KiB [ 2.2% ] /Linux 172.0KiB [ 1.9% ] Solaris.zwc 164.0KiB [ 1.8% ] /Solaris 76.0KiB [ 0.8% ] Darwin.zwc 76.0KiB [ 0.8% ] /BSD 68.0KiB [ 0.8% ] compinstall 64.0KiB [ 0.7% ] /Darwin 60.0KiB [ 0.7% ] BSD.zwc 52.0KiB [ 0.6% ] /Cygwin 48.0KiB [ 0.5% ] /AIX 44.0KiB [ 0.5% ] Redhat.zwc 36.0KiB [ 0.4% ] Cygwin.zwc 32.0KiB [ 0.4% ] Mandriva.zwc 28.0KiB [ 0.3% ] /Redhat 28.0KiB [ 0.3% ] /openSUSE 24.0KiB [ 0.3% ] /Mandriva 20.0KiB [ 0.2% ] openSUSE.zwc 16.0KiB [ 0.2% ] compinit 16.0KiB [ 0.2% ] AIX.zwc 8.0KiB [ 0.1% ] bashcompinit 8.0KiB [ 0.1% ] compaudit 4.0KiB [ 0.0% ] compdump Kind regards, Axel -- /~\ Plain Text Ribbon Campaign | Axel Beckert \ / Say No to HTML in E-Mail and News | abe@deuxchevaux.org (Mail) X See http://www.asciiribbon.org/ | abe@noone.org (Mail+Jabber) / \ I love long mails: http://email.is-not-s.ms/ | http://noone.org/abe/ (Web) ^ permalink raw reply [flat|nested] 8+ messages in thread

At least with regards to the Debian packages: We compile the .zwc for the completions in the source tar ball already at build time, not at install or use time. So they're delivered precompiled in the package anyway.

But to be honest, in OpenWrt users are likely to be running a compressed file system so it may not matter that much. Others (like me) will be running the root FS on top of a USB stick and then space is not that much of a concern. Thanks for the ncdu tip, nice to know about it.
