template problem

[zeysh]

Hi,

Each time I want to use a template with {{ .rootfs }}, the value returned is ""

Ex: with gentoo-stage4 the variable {{.rootfs}} for ROOT in /etc/portage/make.conf

Any idea ?

Have a nice day

I probably introduced this bug. I'm on it

[n0rad]

The problem was in the example. I fixed it.

$ROOTFS exists only when the aci is used in a builder when you run it directly it does not exists so you need an empty string for .rootfs attribute
