Work around for EFI system partition corruption

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Low priority: I'm tempted to nominate this year old bug as a final
blocker under the data corruption provision. And I'm wondering what
people think of this.

RFE: Do not persistently mount EFI System partition at /boot/efi
https://bugzilla.redhat.com/show_bug.cgi?id=1077984

A crash/panic or power failure has a high degree of FAT corruption
potential. The FAT kernel maintainer says this is more or less
expected and that the volume shouldn't be persistently mounted. The
RFE contains a ~18 month (or better) tested work around, using mount
options 'x-systemd.automount,noauto' to prevent it from being mounted
unless needed. At the moment it doesn't autoumount so it can still get
corrupted, but this is better than nothing.

The bug is an RFE so making it a blocker is, well, it's 50% RFE and
50% data corruption bug, and is an odd duck way of getting it fixed
but there's no traction in a year, not even a comment.

The problem came up again today on the systemd list where Kay says
"Right, the Linux FAT driver, or maybe just the way Linux handles the
writeback to disk, is absolutely fragile. Corrupted FAT file systems
are the norm and not the exception. We must mount it unconditionally,
it will just break after a while."

Hence my desire to escalate.
