Subject: [PATCH] Pass corret root= for nfsroot
|
|
|
|
References: bnc#774548, bsc#1069094
|
|
Patch-Mainline: no
|
|
|
|
Fix / is mounted on nfs. The fix is to pass kernel parameters
|
|
with correct root= for nfs. However since grub2 doesn't support
|
|
nfs file system module, the /boot on nfs is not possible and
|
|
grub2-probe not work in probing nfs mounted path. The fix is merely
|
|
on the script level and not use grub2-probe for above reasons.
|
|
|
|
v2: Filter out autofs and securityfs from /proc/self/mountinfo (bsc#1069094)
