Re: if something is not done, hppa will not have an installer for sarge
Including email@example.com as that is where the hppa
developers tend to hang out.
I just had a quick try with
I burnt an ISO, and it wouldn't boot on my B180. It stopped after
'choosing a 32 bit kernel', which I assume indicates some palo
issue. I believe the ISO was burnt ok, because I later loaded
the udebs from it.
Next I copied the 32 bit kernel and initrd.gz from the ISO and
generated a lifimage, using:
/sbin/palo -k vmlinux-2.4.25-32 -r initrd.gz -c 'ramdisk_size=8192 root=/dev/ram initrd=0/ramdisk devfs=mount,dall' -s di.lifimage -f /dev/null
That netbooted and the kernel started ok, but gave continual segfaults
in frontend, as we saw before.
Next I loopback mounted the initrd and copied the libm-2.3.2.so from
my (not very uptodate) sid system to the initrd overwriting the
libm.so.6 on there (which had been reduced to about 1200 bytes).
A workaround for the glibc issue is to avoid reducing libm to the
point where it has no symbols at all.
I gzipped the initrd again and reran palo. The new lifimage booted
ok, used framebuffer, and looks fine. I didn't try modifying any
disk partitions but it found the existing ones ok, including the
palo boot partition which was correctly recognised.
It may be relevant that my palo is 1.3, while the ISO was using
It may be relevant that the ISO had a rather long kernel commandline,
relative to the 127 char limit that palo claims. I'm never sure
whether that 127 char limit is before or after palo adds all the
console and sti related parameters though.
As the ISO I burnt was still in the drive, d-i found that and loaded the
udebs from it. I then went on to select a remote mirror for loading
The install completed successfully, although it installed a 2.4.20
kernel (I guess that is the most recent in testing).
baseconfig worked, although I saw a message in the apt setup stage
briefly that looked like some shell complaint about '['.
Perhaps we should 'fix' mklibs on the system that builds the images to
not reduce libm completely. Then we need to figure out what the palo
This is what i currently have in my mklibs (which I guess worked
round the issue when I last worked on hppa d-i):
# to be the only one and including it on alpha as well
# doesn't hurt. I guess all archs can live with this.
# This is a hack to stop libm being reduced to nothing
+ # RGH.
+ needed_symbols.add(("log", 1))
# calculate what symbols are present in small_libs
present_symbols = Set()
I was surprised to see seperate kernel images, initrd, and iplboot
files on the ISO. I'd say most people netbooted their hppa boxes,
and we should include a complete lifimage rather than the individual
components. It may be that this initrd wouldn't have worked if it
had needed to pull udebs from the net though.
Many thanks to the hppa developers that got us a 2.4.25 kernel for
d-i, and to Jeff for the daily images.
