10. Search is more userfriendly:

yum search python url grabber
yum search kvm manager
yum search application yum




















 9. Repoquery gets features too:

repoquery --installed \
  --qf '%{name} %{ui_from_repo}' 'yum*'

repoquery --installed \
  -a --qf '%{ui_from_repo}' | sort | uniq -c | sort -n

repoquery --installed \
  --qf '%{name} %{yumdb_info.reason}' 'yum*'

repoquery --tree-requires bash | less -S



















 8. Security plugin:

 yum update-minimal
 yum --security update
 yum updateinfo list security all



















 7. Lock specific versions, easily:

# Only all the version of yum currently installed.
yum versionlock add yum
# Opposite, disallow versions of yum currently available:
yum versionlock exclude yum
yum versionlock list
yum versionlock delete yum\*
yum versionlock clear














 6. Create/manage your own .repo variables:

 /etc/yum/vars

 $uuid

 yum repolist -x .
















 5. Yum has it's own DB:

yumdb
yumdb info yum
yumdb set installonly keep kernel-1.2.4-8
yumdb sync

http://yum.baseurl.org/wiki/YumDB















 4. Install is not just for package names:

 yum install 'config(postfix) >= 2.7.0'
 yum install MTA
 yum install '/usr/kerberos/sbin/*'
 yum install @books
 yum -- install @books -javanotes
















 3. Easier to change configuration:

  Any config. option, from the cmd line:

yum --setopt
yum --releasever=14


 Can alter config. files programatically:

yum-config-manager
yum-config-manager --enable updates-testing











 2. We have a full history:

yum history
yum history pkgs yum
yum history summary
yum history undo last

...includes config. options:

yum history addon-info 1    config-main
yum history addon-info last config-main












 1. Syncing machines:

 Are machines the same?

yum version nogroups

 Save/restore:

yum-debug-dump
yum-debug-restore 
    --install-latest
    --ignore-arch
    --filter-types=install,remove,update,downgrade

 Run the same updates:

echo | yum update blah
yum load-ts /tmp/yum_save_tx-2011-01-17-01-00ToIFXK.yumtx
