[gentoo-dev] Customised Gentoo "system"

[gentoo-dev] Customised Gentoo "system"

[Sean Mitchell]

Perhaps I've missed this in the docs somewhere, but I'm not sure exactly
what happens when I "emerge system".

I presume there is a file somewhere that defines "system". What I'd like to
do is create a custom one with a view to building a secure server.

Can anyone shed a little light on this or point me to some docs that will
help?

Thanks,

Sean

Run 'emerge --help system' and you'll see.

emerge [ options ] system

"emerge system" is the Portage system update command.  When run, it
will scan the /etc/make.profile/packages file and determine what
packages need to be installed so that your system meets the minimum
requirements of your current system profile.  Note that this doesn't
necessarily bring your system up-to-date at all; instead, it just
ensures that you have no missing parts.  For example, if your system
profile specifies that you should have sys-apps/iptables installed
and you don't, then "emerge system" will install it (the most
recent version that matches the profile spec) for you.  It's always a
good idea to do an "emerge --pretend system" before an "emerge
system", just so you know what emerge is planning to do.

  after reading through the portage users guide[1] I haven't found any
  easy way of upgrading all packages that can be updated
  automagically. is there any planning on doing this? :)

The answer is quite informative, but what is "your current system
profile"?

/etc/make.profile is a symlink that points to your current system profile,
which normally resides in /usr/portage/profiles.  Right now, it should be
the "default" profile.

Perfect. The more I learn about this little beauty the more I like it!

So basically all that's needed to create a custom gentoo based distro is to
edit the /etc/make.profile/packages file.

Cheers,

Sean

Well, /etc/make.profile is a symlink to /usr/portage/profiles/default, so any
changes you make inside /etc/make.profile will be erased the next time you do
an emerge rsync.  A better technique is to copy /usr/portage/profiles/default
to another location outside of /usr/portage (/etc would be fine) and then hack
away.

It's planned, but not ready yet.  I'm going to add an entry to 
the FAQ about it, since we get asked this question a lot.

  okay, thanks.

  okay, sorry. I thought I'd read the mailinglists a bit more
  carefully than to ask a silly question again. :/
