F15 - 640MB RAM Requirement Issue
 
Hi,

I
have been using F15 Beta for almost a month now. I currently have 512MB RAM and I must say, it has been working fairly normal (in fact the experience) was better then when XP was on the same machine. I was a bit surprised to know that installing F15 Final requires a minimum of 640MB RAM and what was more surprising that the installation will not proceed. Moreover, F15 Final running from the Live CD was working quite usual and there was little impact on performance, of course, besides the typical Live CD performance constraints.
I was just curious why was this (blocking of
installation) done on the F15 Final Release and more so why is it not allowing the installation instead of, lets say, giving some kind of warning and proceeding. I was also wondering if there is some way around it?
Thanks!

F15 - 640MB RAM Requirement Issue
 
Hi,
Thanks! For the reply. But yum itself is horribly slow on F15 beta. I rarely get above 7 Kbps, which makes online upgrade very frustrating. I even tried a lot of suggestions over the web for changing mirrors, configuring name-servers etc., none helped. But,
things seem to be working fine on the Final Release Live CD.RegardsFrom:*Leonid Podolny <leonidp@gmail.com>

My guess would be that an upgrade using yum (http://fedoraproject.org/wiki/YumUpgradeFaq) would be such a workaround. Anaconda is not involved, so there is nothing to check the minimum RAM requirement.

This may not help now, but you should install the presto and
fastest-mirror plugins for yum. Presto only downloads delta-rpms (They
only contain what's changed since the last time they were updated.) and
rebuilds the rpms on the fly. This can save at least 80% of your
download time. Between the two of them, they can make updating your
system much faster.

It's a trade-off. If you have a fast internet connection but a slow
processor you might actually be better off downloading the full rpm
instead of waiting for your processor to decompress and/or merge the
deltas.

True. However, I inferred from what the OP wrote that the download time
was an issue. And, if you stop and think about it, it probably is. F
15 just came out; lots of people have just upgraded to it and are
sucking down whatever updates have come out since F 15 was finalized.
This can be slowing down the downloads until things stabilize. If so,
presto can be a big help.

The OP stated that he had problems with the F15-beta updates. His
download speed improved when F15 reached final.

Hi,

It does not seem that the slow speed is due to high load on F15 servers, I guess it is a problem with the beta. I have got decent processor and I don't think simultaneously downloading and processing would be an issue.

I guess, I will try with presto and see how it can help. But, I hope that further installers do not discontinue the installations when minimum requirements are not met.

Why? What reason would there be for the installer to continue if the
system doesn't have enough RAM for the installer to complete the
installation or there's not enough free space on the hard disk to put
everything (plus scratch space for the installer to work)?

There is no reason to continue an installation guaranteed to fail.

What has been disputed lately is that the installer needs that amount of the system resource to run. That raises the question why the installer prevents installations on machines that meet system requirements for full Fedora 15 with GNOME or whatever but not being able to run the installer. And a possible solution is already being searched for.
