Subject: [devuan-dev] Is there a way to increase the memory usage of a "live" Devuan boot?

Devuan types :

     I have devuan_daedalus_5.0.preview_20230501_amd64_desktop-live.iso
and tried to boot it in a VMware vm with 32G of memory. Which seems to
work. However if I try to install a few packages as well as build the
OpenZFS modules then it claims I am all out of space. Or worse.


     There seems to be an option simply called "live" and another option
called "toram" in the grub menu options. If I select the "toram" menu
option and edit that for ipv6.disable=1 with verbose and net.ifnames=0
then I seem to get a sane desktop with DHCP doing its thing. I can
then install openssh-server and then even ssh into the thing.


     Once I have a reasonable root level shell in the live install image
I try to install the zfsutils-linux package with a few things :


m# apt-get install debootstrap gdisk parted ed bc dc time fdisk
zfsutils-linux


* * * That eventually fails due to : "No space left on device" * * *

Is there an easy way to get a *LOT* more usable space in the "toram"
boot option for a live image?
