Re: How much mem is low, exactly?

What is the target memory for the lowmem installation?
24 MB seems not to work.  I had the hope, that ca. 16 MB
would be the limit.

25-45 MB, depending on architecture.

Some ideas for improvements:

1. Disable certain downloads/features.  IMHO it is OK to
  have a lowmem install with less features, e.g. LVM, RAID,
  other FSs than EXT3/EXT2, etc.  Who would use a 16 MB
  machine with SW-RAID? :-)

2. Let the user select downloads/features.  If the user does
  have SCSI, SATA, etc. why download the stuff and eat RAM
  disk space?

3. Let the user earlier create the partition table and the
  swap space (and acitvate the latter) and download other
  udebs later.

4. Use text instead of ncurses for debconf (lowmem is
  English-only anyway).

What do the d-i people think?

You may want to read packages/lowmem/README in the SVN repository.
The main reason the "lowmem" mode is so ineffective is that nobody
did so far the work to make it better.


i have changed anna to enable the user to select what he wants.
and anna only download the selected packages (and dependencies too)

the current status is:
- i succeed to install in 24Mb (i select plip+partman-auto)
- i do not test with lesser memory (because i use plip for testing and i currently can not use it, but this will be resolved in few hours)
- of course, the memory depends on which packages you have selected
- there is not enough time to include this patch for release rc1, so according with joey, i will create specific images for very lowmem PCs

i will send you the patch on the list , if someone wants to test it ;)
