# Alpine initramfs doesn't contain dm-mod or fuse module,
|
||
|
|
# and even the worse, the libpthread.so is not included too.
|
||
|
|
# So here we directly dump the modloop squashfs file from disk to rootfs.
|
||
|
|
# Fortunately, this file is not too big (< 100MB in alpine 3.11.3).
|
||
|
|
# After that:
|
||
|
|
# 1. mount the squashfs file
|
||
|
|
# 2. find the dm-mod module from the mountpoint and insmod
|
||
|
|
# 3. unmount and delete the squashfs file
