Convert to and from Gentoo Fedora

WHAT

I use two main linux distros. Fedora on my own boxens and desktop/laptop and gentoo on the gateway, devel boxens and other servers. And I kinda' mess them up. Here's what I usually mess.

Difference

Updating the package database

This command only checks to see if new packages are avaiable, and will not install anything onto your computer. Yum actually updates its list of packages at every run, unless you use the -C option to use the cached list.

Fedora

yum check-update

Gentoo

emerge --sync

OR

emerge-webrsync (If rsync does not work)

Update All Packages on your system

This command will actually install all of the updates on your system. The default behavior in yum is to ask before actually installing the updated packages; this behavior is replicated in emerge through the use of the --ask (-a) flag.

Fedora

yum update

Gentoo

emerge -aDv world

Installing a specific package

This will install only specific packages. You can install more than one if desired.

Fedora

yum -y install app1 app2

or

yum install app1 app2

Gentoo

emerge app1 app2

or

emerge -a app1 app2

Reinstalling a single package

Following the same pattern as above, more than one can be done at a time if desired.

Fedora

yum update app1

Gentoo

emerge --oneshot app1

Searching for packages in the database

Fedora

yum search app1

Gentoo

emerge --searchdesc app1

Note: On Gentoo, it's actually much better to install and use either the esearch package or the eix package to do a search. This is because they cache the searches, and are much faster than using emerge --search. You use them like so:

eix searchword

or

esearch searchword

Removing a package

Fedora

yum remove app1

Gentoo

emerge --unmerge app1

Services

To stop/start/whatever a service, you need to call the /etc/init.d script directly. There is no "service" command.

To enable/disable service on boot:

Fedora

chkconfig <service> on
chkconfig <service> off

to specify runlevel:

chkconfig --levels 235 <service> on

Gentoo

rc-update add <service> <runlevel>
rc-update del <service> <runlevel>

i.e.:

rc-update add apache2 default
rc-update del alsasound boot
