[pve-devel] [PATCH installer 1/2] low level: config: filter out kernel cmdline on word boundaries

[Christoph Heiss]

Otherwise, substrings might get replaced, e.g. the replacement
`proxmox-start-auto-installer` -> `pxmox-start-auto-installer` would be
done.

Fixes: a02a78a ("fix #4747: pass kernel cmdline parameters to target system")
