Subject: [PATCH] Fix detection of 'macefi' partitions (#1393846)
|
|
|
|
368a4db6 lost a crucial condition in the detection of 'macefi'
|
|
partitions in the transition to the 'populator helper' design.
|
|
Previously we checked that the parted partition 'name' (which
|
|
is a GPT property, for GPT partitions) matched the expected
|
|
value according to the macefi format, which basically means we
|
|
will only detect partitions created by a previous anaconda run
|
|
as 'macefi' (because that name is a very specific one which is
|
|
only created by anaconda in the first place).
|
|
|
|
In the transition, that condition was lost, and now we treat
|
|
any device with an HFS+ filesystem that's over 50MiB in size
|
|
as a 'macefi' device, which means we mount it at /boot/efi and
|
|
try to write all kinds of stuff to it. Not surprisingly, this
|
|
borks the install. Fortunately, HFS+ filesystems are mounted
|
|
read-only unless they have journalling disabled, so this won't
|
|
result in us messing up people's OS X partitions with any luck.
