danmcd_, I'm trying to overlay /etc/system on a bootable pool, on the USB stick mounted at /mnt/. Normally, I place the files in /mnt/bootfs/etc and loader.conf.local in /mnt/boot. I saw that you made a post where you mentioned that on bootable volumes we can place files in /zones/boot/custom to make sure the changes are applied to all releases... can you confirm this? ...because it doesn't seem to be working for me.

That works for "future installed boot images". From the piadm(8) man page:

"Loader config files can also be placed in ${BOOTFS}/custom, and will be used by all subsequently installed boot images, but not existing ones."

So I'd recommend:

- Set up $BOOTFS/custom

- Install the next SmartOS update (which is built, but not officially blessed-as-released yet, but will be by tomorrow)

- Boot the next SmartOS update

That needs to be done in-order, per the man page's "subsequently installed boot images".

Therefore, the paths will be /zones/boot/custom/loader.conf.local and /zones/boot/custom/etc/system ...correct?

Depends on what you put in there. It works like it did on the usb key. Here's examples I have for ppt:

(gist link coming soon...)

If you really need an old PI, you can hand-hack the $BOOTFS's `boot-XXXXX` directories.

And it's not a function of the PI, it's a function of the boot-XXXX directories. This is why we encourage updates from ISO. (We need to at some point allow piadm(8) to take a boot-XXXX.tgz + platform-XXXX.tgz to shrink things.)

danmcd, I need to change the maximum arc usage and passthrough

So the sample gist above will need you to uncomment some lines for /etc/system, and optionally the path if you don't wanna put them in $BOOTFS/system like I did.

s/optionally the path/optionally change the path in the custom\/. file/g

danmcd, solved ...a simple page in wiki will be appreciated

thank you
