Discoveries

This page contains random discoveries that we make. We’ll bring some structure to this page as we go.

Techniques

--nodocs or --setopt=tsflags=nodocs
- Average shrink is 5 to 10M
--setopt=install_weak_deps=false
- Depending on the package could shrink alot, could shrink nothing
- Can remove some functionality
install glibc-minimal-langpack <package(s)>
- Average shrink is 200M
- Can remove some language based functionality

These headings can/should be changed. They are what they currently are just for placeholders.

httpd
- Remove systemd from main package
- https://src.fedoraproject.org/rpms/httpd/pull-request/7
  - /usr/sbin/apachectl requires /usr/bin/systemctl so this will require some package/subpackage shuffling.
nginx
- Remove systemd from main package
- https://src.fedoraproject.org/rpms/httpd/pull-request/5
mariadb
- Drop perl ?
  - The two perl scripts in mariadb (mysqlaccess and mysql_find_rows) and might be considered being moved to a sub-package -client-utils, similiar to the perl scripts in -server-utils.
- Drop systemd ?
  - The mariadb containers start with run-mysqld. systemd is not involved at all.

postgresql
- Drop systemd ?
systemd
- Can we pull it out of more package dependencies
- https://pagure.io/minimization/issue/2
- Systemd is in all Fedora containers due to a bug in anaconda. Although the bug has been fixed, updating the koji image builders still hasn’t happened.
polkit
- Currently depends on mozjs60
  - It’s rather large, (25M - 30M) can it be removed from some package dependencies ?
  - Possibly use duktape instead of mozjs
  - Request for information has been sent out, no replies yet.
perl
- It’s rather large, can it be removed from some package dependencies ?

dnf [changed]
- removed systemd as a dependency. Dropped container size by 30M.
anaconda-core [not-changed]
- Can we shift flatpack-libs dependency to anaconda-gui ?
- https://src.fedoraproject.org/rpms/anaconda/pull-request/5
  - No, it needs to be where it is.
