>Description:
Mid-December, 2001 on stable@freebsd.org, we see this thread:
Re: Waaaarg, we just blew out the kernel again..
Not the first time, probably not the last time either ;-)
>How-To-Repeat:
make release of -stable branch, it will fail because the GENERIC floppy
overflows (Mid-December 2001).
>Fix:
As I mentioned in stable@freebsd.org on Tue, 18 Dec 2001
in Message-Id: <200112181133.MAA11130@marabu.marabu.ch>
... a brighter future is indeed to modularize more drivers ...
As a stopgap, we can try to compress GENERIC better:
Here we have a patch to replace the gzip compression with 'bzip -1'
in src/release/Makefile. It has been tested: sysinstall went fine
on a custom-burnt CD made from the .../R/cdrom/disc1/ tree.
BTW, these are the savings on kern.flp with the bzip-only loader:
$ df -ik /mnt
Filesystem 1K-blocks Used Avail Capacity iused ifree %iused Mounted on
/dev/fd0a 1407 1385 8 99% 5 25 17% /mnt
$ ls -l /mnt
total 1297
drwxr-xr-x 2 root wheel 512 Dec 22 02:10 boot
-r-xr-xr-x 1 root wheel 1320875 Dec 22 02:10 kernel.bz2
I have also checked that the loader can indeed load kernel.bz2 images.
Since this change is quite intrusive, a second independent
test should be done before commiting. Also, there might be
a better place to add the LOADER_BZIP2_SUPPORT=YES
LOADER_NO_GZIP_SUPPORT=YES flags than straight into
WORLD_FLAGS. One might even consider changing the default
in the loader's Makefile.
