Subject: [PATCH] man: mention that sd_id128_get_boot() and friend may return
|
|
-ENOSYS
|
|
|
|
And drop to mention sd_id128_get_boot_app_specific() may return -ENOENT
|
|
or -ENOMEDIUM. The function does not read /etc/machine-id. But reads a
|
|
file in the procfs, which is a kind of the kernel API. Hence the
|
|
failures are caused only when the system has wrong setup.
|
|
|
|
(cherry picked from commit c576920e673114529c5bfe5ea29891a24a443338)
