[Feature Request] Option to disable hardware/block device collection (dmidecode/blkid) for LXC environments

[magenbrot]

I am running proxsave inside an unprivileged LXC container (with Proxmox Backup Server) on Proxmox. While the backup process works perfectly, the logs are constantly flooded with warnings because the container lacks permission to access low-level hardware information:

WARNING Skipping Block device identifiers (blkid): command blkid failed (exit status 2).
WARNING Skipping Hardware DMI information: command dmidecode failed (exit status 1).

This is expected behavior for secure LXC containers (denied access to /dev/mem and block devices), but it generates unnecessary noise in the logs and notification channels, making it harder to spot real issues.

I would like to see a configuration option in backup.env to explicitly disable these hardware collection steps.

For example:

# Disable hardware inventory collection (useful for LXC/Docker)
COLLECT_HARDWARE_INFO=false

If set to false, proxsave should skip the calls to dmidecode, blkid, sensors, and smartctl entirely, avoiding the warning logs.

Hi, a correction/improvement will be included in the next release.

We are implementing automatic detection of lxc environments without privileges. In those contexts, ProxSave will still attempt to perform the entire collection (so even false positives will not be damaged) and will downgrade any warnings for absences from warnings to info.
