Subject: [PATCH 00/13] erofs-utils: mkfs: introduce rebuild mode
Date: Mon, 14 Aug 2023 11:42:26 +0800 [thread overview]
Message-ID: <20230814034239.54660-1-jefflexu@linux.alibaba.com> (raw)
Introduce a new rebuild mode merging multiple erofs images generated
from either tarerfs index mode (--tar=i):
mkfs.erofs --tar=i --aufs layer0.erofs layer0.tar
...
mkfs.erofs --tar=i --aufs layerN.erofs layerN.tar
mkfs.erofs merge.erofs layerN.erofs ... layer0.erofs
or tarerofs non-index mode (--tar=f):
mkfs.erofs --tar=f -Enoinline_data --aufs layer0.erofs layer0.tar
...
mkfs.erofs --tar=f -Enoinline_data --aufs layerN.erofs layerN.tar
mkfs.erofs merge.erofs layerN.erofs ... layer0.erofs
The rebuild mode doesn't support flat inline datalayout yet.
