Stressant

we should have a shell script that we can run after login, or that runs straight on boot, and that will run all the tests we need.

so far, i have this in the motd:

This debirf image has the "stresant" extensions. Some suggested tests:

# hardware inventory
lshw -short
lshw -json | nc backup.example.com 12345
# basic hard drive speed test
hdparm -Tt /dev/sda
# wipe disks
${wipe_motd} /dev/sda
# benchmark disks with bonnie++
mkfs -t ext4 /dev/sda # only on new systems!
mount /dev/sda /mnt
chown nobody /mnt
free -h
bonnie++ -d /mnt/ -s 96G -n 1024 -u nobody
# cpu stress testing
stress -c $(grep ^processor /proc/cpu | wc -l)

some fixes needed there:

• detect existing partitionning and mount instead of mkfs for bonnie test, abort to be safe in doubt
• calculate bonnie ram automatically
• log output (where?! email? syslog UDP??)
• show this on the first tty by default?
