Subject: [pve-devel] [PATCH pve-kernel-meta] proxmox-boot: trim /etc/kernel/cmdline before appending
Date: Wed, 10 Nov 2021 15:15:11 +0100 [thread overview]
Message-ID: <20211110141511.3617927-1-s.ivanov@proxmox.com> (raw)
following the commit of removing the wrong indentation of the linux
and initrd lines - this commit strips empty lines (and leading
trailing whitespace) in /etc/kernel/cmdline.
I managed to reproduce the issue reported in the forum [0] by adding
empty lines to /etc/kernel/cmdline) - without this - systemd-boot
booted quite happily even with the indentation.
quickly tested on a VM.
