Subject: [PATCH] 10_linux: Ensure persistence of root file system mounting
|
|
|
|
This commit addresses the issue where the by-uuid or by-partuuid device
|
|
symlinks might be unavailable in an installation system. Despite the
|
|
absence of these symlinks, the resulting system remains fully functional
|
|
for mounting the root file system by using persistent names
|
|
(root=(UUID|PARTUUID)=).
|
|
|
|
The patch implemented in this commit aims to prevent fallback to the OS
|
|
name as the root= parameter, as persistent names are preferred for
|
|
stability and predictability.
|
|
|
|
To achieve this, the fallback to the OS name won't be triggered if the
|
|
corresponding by-uuid or by-partuuid symlinks are missing, ensuring the
|
|
use of persistent names. Instead, a warning will be logged for the
|
|
missing symlinks, providing visibility into the issue.
