Testing Notes¶

Existing persistent installation system¶

On a stock OpenIndiana system, I installed my test build of the change and checked that the helper program worked as expected:

root@oi0:~# /lib/svc/bin/rootisramdisk -v
major = 259
driver = zfs
root@oi0:~# echo $?
3

I also edited the following files to add -x to the sh arguments in interpreter line so that I could see the debugging output:

• /lib/svc/method/boot-archive
• /lib/svc/method/boot-archive-update

In particular, note that the service continues after the smf_root_is_ramdisk function and proceeds to run the boot archive check.

root@oi0:~# tail -n 50 $(svcs -L boot-archive)

Ramdisk system¶

I build a basic ramdisk, effectively using pkg image-create to install a bare bones illumos system into a ramdisk that I then wrapped in a UFS file system image and a bootable ISO, in a fashion similar to installer miniroots. Before the change, we would see a warning about needing to update the boot archive on the console. After the change, this no longer happens. The helper also appears to work as expected:
