Subject: [pve-devel] [PATCH pve-kernel-meta 6/7] proxmox-boot: add grub.cfg header snippet
Date: Thu, 22 Apr 2021 13:17:59 +0200 [thread overview]
Message-ID: <20210422111801.4193-7-s.ivanov@proxmox.com> (raw)
In-Reply-To: <20210422111801.4193-1-s.ivanov@proxmox.com>
If the system seems to be booted using proxmox-boot, write a header at
the beginning of the grub.cfg generated when running `update-grub`
Additionally print a warning in case the script is run interactively.
This is determined by checking for DPKG_VERSION, which is set when
running as post-inst task (after a kernel install/removal)
and for PVE_EFIBOOT_UNSHARED, which is set by proxmox-boot-tool when
running `proxmox-boot-tool refresh.`
