[pbs-devel] [PATCH v5 proxmox{, -backup} 0/5] Add boot_mode, improve kernel version

[Gabriel Goller]

Ported the recent changes from the PVE NodeSummary (done by @Thomas) to
the PBS NodeDashboard.

It consists of:
* Adding the bootmode field, shows either Legacy BIOS, EFI, or EFI
    (Secure Boot)
* Declutter the kernel-version field and only show the release version
    and build-date.

Changes since v3:
  * Rename function
  * Substitute lazy_cell + Mutex with std::sync::OnceLock

Changes since v3:
  * Split functions into BootMode and SecureBoot status

Changes since v3:
  * Removed leftover debug print

Changes since v2:
 * Return the exact same stuff as in pve, so create a struct that holds
    mode and secureboot boolean
 * Fix indentation in js
 * Add efi spec link

Changes since v1:
 * Moved boot_mode detection to proxmox-sys
 * Added caching to boot_mode detection (lazy_static)
 * Return legacy kernel-version as well

[pbs-devel] [PATCH v5 proxmox 1/5] sys: add helper to get bootmode and secureboot status

[Gabriel Goller]

Helper that return the current boot_mode and secureboot status.
Detection works the same as in pve, we use `/sys/firmware/efi` and
the `efivars/SecureBoot-xxx..` file.

[pbs-devel] [PATCH v5 proxmox-backup 2/5] node: status: added bootmode

[Gabriel Goller]

Added field that shows the bootmode of the node. The bootmode is either
Legacy Bios, EFI, or EFI (Secure Boot). To detect the mode we use the
exact same method as in pve: We check if the `/sys/firmware/efi` folder
exists, then check if the `SecureBoot-xx...` file in the `efivars`
directory has the SecureBoot flag enabled.
