Does anyone have a useful Linux running on zSeries that is less that 24MB
with OSA? With LCS? It looks like OSA is a good chunk of code.

I put together a SuSE SLES8 SP2 mimum system (no graphics) and played a bit
with memory size. I manipulated mem=??m in /etc/zipl.conf.

Some conclusions:

1 - I could not ipl in 8m - I got a kernel panic
2 - I could IPL with 12m, but it did not load the OSA code.
3 - I could IPL at 24m and load the OSA. After starting an ssh login
sessions and mounting 2 NFS mounts, there was 3372 bytes, on the swap
volume.
4 - at 32m, the swap usage when to zero.

At 24m, I could login with ssh and mount 2 nfs volumes.

The configuration was for 2 CP. There was not a large variance between LPAR
and EC (about an additonal 68 useable bytes under LPAR).

SuSE wants to start the following processes:

init
migration_CP (1 per CP)
kmcheck
kvventd
ksoftirqd_CP
kswapd
bdflush
kupdated
kinoded
mdrecoveryd
kreiserfsd
lvm-mpd
qethsoft
syslogd
klogd
portmap
sshd
master
pickup
qmgr
atd
cron
nscd (7 copies)
login
