Subject: fix(dmsquash-live-autooverlay): re-read partition table after creation
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=99d25ea0f81881c5a5eeada00d2ee7e08c28c69c;p=thirdparty%2Fdracut-ng.git

fix(dmsquash-live-autooverlay): re-read partition table after creation

After parted creates the overlay partition, the kernel's in-memory
partition table is not automatically updated. This causes mkfs to fail
with "The file /dev/sdX does not exist" on some systems.

Add blockdev --rereadpt to force the kernel to re-read the partition
table before attempting to create the filesystem.
