Subject: [PATCH] lvm: fix thin recognition
|
|
|
18971c |
|
|
|
18971c |
The global var setting was happening in a pipe and did not have an
|
|
|
18971c |
effect.
|
|
|
18971c |
|
|
|
18971c |
Use <<<$() instead.
|
|
|
18971c |
|
|
|
18971c |
< <() cannot be used, because dracut is called in chroot's environments,
|
|
|
18971c |
where /dev/fd does not point to /proc/self/fd, but bash wants
|
|
|
18971c |
/dev/fd/<num> for this construct.
