Package: boot-floppies
Severity: wishlist
Perhaps this should be a post to -devel or -policy, but I'm not a
developer so I would feel funny especially in -policy....
With a 2.2.x-sized kernel, we obviously need to start thinking about
saving space on resc*.bin. My idea is to drop things like SCSI, IDE,
quota, kerneld, ext2, etc. from the kernel image. SCSI/IDE/ext2 would
be loaded from modules during installation. This poses several
problems, of course:
o (Unless we do the RedHat mkinitrd thing, which I don't like...) We
still need a full-blown kernel image for after the reboot, thus
bloating base*.tgz. And I'm not sure drv*.bin has room for the extra
modules either.
o Modules for immediate disk use (ide-hd, xt, SCSI, md, maybe parport
and pcmcia) would have to be loaded before partitioning, meaning long
before the main modules get untarred. So, two separate passes of
module config; not optimal.
o Possibility that the "full" kernel doesn't boot for someone where the
"minimal" kernel does. No worse than current situation really,
except that it would confuse the user a bit.
o resc1440.bin would no longer be too good as a rescue disk. The way
to solve that (imho) would be to have a separately packaged script
(included in loadlin or boot-floppies) to create a custom rescue disk
with your real kernel on it and without things like dbootstrap.
On the other hand it would cut down on the absolute minimum memory
required for installation....
What would make this so much easier is if there were a system by which
a kernel could load modules without mounting either root or initrd. I
envision a modified `insmod' that relinks a kernel image instead of the
running kernel. Currently I'm in the research/design stage of trying
to implement this. You guys will be the first to know if I ever get it
working.

boot-floppies (2.2.3) unstable; urgency=low
* busybox: updated to 0.40; fix logger; remove free (use lazybox free
instead, which is better)
* dbootstrap: 'expert' boot argument skips some annoying confirmation
dialog boxes; fix kbdconfig dialog being too big; fix the 'list'
archive selection method for installing kernel; more debugging and
informative messages piped to syslog; on i386, install mbr using
/sbin/install-mbr; for m68k, fix keyboards; when doing 'list' method
of disk or mounted archive location selection, just do it if we only
have one possibility
* root: add lazybox 'man' command, reminding users to install man-db pkg
* debian/copyright: remove old FSF address; add/re-organize busybox,
lowmemrd, dbootstrap copyright information (lintian)
* debian/control: standards version 3.1.1; depend on gcc, file; change
priority to extra
* debian/rules: debhelperify; binary package contains the tarball
/usr/src/boot-floppies.tar.gz, rather than the unpacked files in
/usr/src/boot-floppies/
* i18n: Hungarian, Russian, French, Portuguese updates
* powerpc: add amiga-fdisk to base and root
* close bugs from last release (closes: Bug#52073, Bug#41193, Bug#30959)
* we split root/boot now, maybe we'll do initrd or some such for woody,
but lets close this bug (closes: Bug#40160)
* README clarifications (closes: Bug#41189)
