From aabea6f7b9c057571d1869c6974d4c4f42530e7e Mon Sep 17 00:00:00 2001 From: Harald Hoyer Date: Wed, 16 Oct 2013 11:30:08 +0200 Subject: [PATCH] lvm: fix thin recognition The global var setting was happening in a pipe and did not have an effect. Use <<<$() instead. < <() cannot be used, because dracut is called in chroot's environments, where /dev/fd does not point to /proc/self/fd, but bash wants /dev/fd/ for this construct. --- modules.d/90lvm/module-setup.sh | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/modules.d/90lvm/module-setup.sh b/modules.d/90lvm/module-setup.sh index f8b598d..cbdf4a2 100755 --- a/modules.d/90lvm/module-setup.sh +++ b/modules.d/90lvm/module-setup.sh @@ -57,12 +57,13 @@ install() { inst lvm if [[ $hostonly ]]; then - get_host_lvs | while read line; do + while read line; do + [[ -n "$line" ]] || continue printf "%s" " rd.lvm.lv=$line" if !
