[Fedora-livecd-list] Trimming the size of LiveCD's

[Elias Hunt]

I'm just getting caught up on some old threads, but saw this one and
wanted to add another voice in support.

Since rpm itself already supports the --excludedocs argument, does yum
support passthrough? If so could livecd-creator also support passthrough
in some way? I looked at the livecd-creator code in hopes of being able
to submit a patch myself, but I understand entirely too little of the
yum api and whether or not it would support passing along standard rpm
arguments or if yum itself might need to be modified.

In the past when we did our own custom spins (not livecd-creator based)
I used to do cleanup of info, man, docs, etc by removing the files from
my master image. This allowed all spins to not even have to think about
those files. As was suggested in this thread the files could be removed
in the %post section, however that means time, disk and RAM would be
utilized during the spinning process to install and then delete the
files. If they never got installed in the first place it seems like the
whole thing would be smoother.

In our case we'd never want those files back as we don't install off
livecds, so having a tool to fix would be inconsequential. Obviously
this should never be enabled by default, but for many of us making
custom spins it seems like a quick way to remove a lot of excess data at
a cost we'd be willing to bear.

If there is already an argument available in kickstart, yum or
livecd-creator that can do this, I'd appreciate the slap on the wrist
and being told I should pay more attention. :)

Thanks.

Perhaps a switch will enable --excludedocs on rpms being installed into
the live-cd and a tweak to yum would enable someone who liveinsts the
livecd to a disk to type run some new cmd like "yum updatedocs" or
something that gets the docs back?

To take this another level, stuff in rpms can be flagged as necessary /
extra and there can be an --excludeextras flag during rpm install and a
yum updateextras or yum installextras command to go add these back in?

Thanks,

MoeK

It seems to me that if a livecd removes shit to save space, and anaconda
can still use a CD with RPM's on it, the problem of not being able to
install from a LiveCD is solved; Install from a LiveCD with stripped
contents using another CD that holds the RPMs.

However this may not be applicable to any of the Live Media the Fedora
Project releases, I see a use-case for *anyone else* wanting to produce
Live Media.

Back to the original topic; what could we possibly remove without all
"help" functions b0rking. I'm thinking INSTALL, ChangeLog/CHANGES,
README, etc files, as well as maybe a number of non-prominent utility
documentation sets (from the end-user POV, zlib-x.x.x documentation
really isn't relevant). For some packages even, we could maybe remove
the man pages as well (--excludedocs in extreme cases?)
