Anyone knwo how to give mount option in the autoinstall config ?
i tried different method without success.
it’s my user-data conf but the mount option is ignored during the install :
#cloud-config
autoinstall:
version: 1
interactive-sections:
– network
locale: fr_FR
keyboard:
layout: fr
variant: fr
identity:
hostname: ubuntu-server
username: ubuntu
password:
storage:
config:
– grub_device: true
id: disk-vda
name: ”
path: /dev/vda
preserve: false
ptable: gpt
type: disk
wipe: superblock
…….
…….
…….
– device: format-9
id: mount-10
path: /tmp
type: mount
options: ‘nodev,noexec,nosuid’
– device: format-10
id: mount-11
path: /data
type: mount
options: ‘nodev,noexec,nosuid’
– device: format-11
id: mount-12
path: /var/log
type: mount
options: ‘nodev,noexec,nosuid’
…….
…….

but when i check the code of curtin => https://github.com/canonical/curtin/blob/ubuntu/focal/curtin/commands/block_meta.py in line 1196 the options exist .
def mount_handler(info, storage_config):
“”” Handle storage config type: mount
info = {
‘id’: ‘rootfs_mount’,
‘type’: ‘mount’,
‘path’: ‘/’,
‘options’: ‘defaults,errors=remount-ro’,
‘device’: ‘rootfs’,
}
Mount specified device under target at ‘path’ and generate
fstab entry.
“””
state = util.load_command_environment(strict=True)
mount_apply(mount_data(info, storage_config),
target=state.get(‘target’), fstab=state.get(‘fstab’))

if it works as I expected, I can put the options nodev | noexec | nosuid … an idea?
