Temp file aka loop device on custom location

[niekvanderven]

Can I manipulate the location of the loop device as my partition table is custom setup and overloading:
df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 4.0M 0 4.0M 0% /dev
tmpfs 126G 0 126G 0% /dev/shm
tmpfs 51G 15M 51G 1% /run
/dev/mapper/rl_kvm02--nikhef-root 16G 16G 365M 98% /

tmpfs 26G 16K 26G 1% /run/user/0

Hello @niekvanderven,

d2vm uses os.TempDir(), so the temp image and loop device location can be controlled via the TMPDIR environment variables.

For example:

TMPDIR=/path/on/your/partition d2vm build …

Let us know if TMPDIR works for your setup.

Hi, thank you for the prompt reply, much appreciated !!!
So far it runs lets see if it also work what I was intended to achieve.
Output of succesfull command:
TMPDIR=/var/lib/libvirt/iso/ ./d2vm convert ghcr.io/nokia/srlinux -o /var/lib/libvirt/iso/srlinux.qcow2 -p MyP4Ssw0r
