A possibility is dropping os-prober in lowmem mode. I guess that most users installing in low memory conditions will be skilled enough for configuring a dual boot later. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

IMHO, the goal for lowmem on ia32 should be Countrychooser can probably be optional in lowmem mode. After all, its only purpose is building a valid locale value and lowmem feeds this value (see the recent change I made to it after the new languagechooser broke it) This needs testing, however. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

This patch is good - I can now partition on my 24 MB machine. It seems that the memory limit is now about 21.5 MB (for i486, stone age hardware). Thanks a lot! Issues: - In lowmem mode, the installer now asks some questions more than one time. This is acceptable of course. - The partitioner did not give me the choice 'all in one - recommended for new users', but only 'separate home dirs'. Maybe I did sth. wrong? - There is room for improvement: Some tools were installed without my consent/need: os-prober, lilo-installer, nobootloader - I can't remember all, sorry. Also I'm not sure, whether the countrychooser could be optional for lowmem. IMHO, the goal for lowmem on ia32 should be around 16 MB, depending on the hardware. Questions: - Is there any chance, that Sylvains patch (that works perfectly for me) will be accepted soon? - Is it possible (and worth), to leave out the countrychooser? - Is it possible to not load os-prober, lilo-installer etc. in lowmem mode?

It would be nice to have the patch in (if it works) - that would
lead to better testing than lowmem-specific images, I believe.
