Subject: [PATCH] udev: restore compat symlink for nvme devices
|
|
|
|
In 5118e8e71dda211d20e34ec8d3012186ba27d3d3, the rules were changed to add
|
|
OPTIONS="string_escape=replace" to creation of
|
|
ENV{ID_SERIAL}="$env{ID_MODEL}_$env{ID_SERIAL_SHORT}", so that "/" would be
|
|
escaped. But this also changes how the symlink looks for devices that do not
|
|
have "/". This adds back the old symlink for compat, except when a slash
|
|
is present.
|
|
|
|
In the meantime, we changed the symlink format to include ${ND_NSID}. Since
|
|
the symlink with unescaped characters are older than that, for compat we
|
|
only need to cover the older type. (Symlinks without escaping and with ${ND_NSID}
|
|
were never created.) This makes it slightly easier on users: the non-deprecated
|
|
symlinks are with "_${ND_NSID}", so they are easier to distinguish.
|
|
|
|
Fixes #27155.
|
|
|
|
Mostly untested :( I only have a boring nvme device with no special characters
|
|
in the id, and the symlinks are unchanged for it by this patch.
|
|
|
|
(cherry picked from commit d05e1be86e6b14bd22d57af17efcc3b8fb7ecd82)

[msekleta: it is not strictly necessary to include this commit in RHEL-9
|
|
because the we never had the previous version of non-escaped symlinks in
|
|
RHEL-9. However, by including it we are making a life a bit easier for
|
|
folks that are doing in-place upgrade from RHEL-8.]
