Subject: [PATCH v3 00/11] erofs-utils: mkfs: introduce rebuild mode
Date: Tue, 22 Aug 2023 17:24:46 +0800 [thread overview]
Message-ID: <20230822092457.114686-1-jefflexu@linux.alibaba.com> (raw)
v3:
- the original v2 patch [1] is split into patch 1 and 2
- patch 3 is new fix
- patch 6: trusted.overlay.opaque xattr won't be stripped in the mrged
view
- patch 8: whiteout is droped only when the object (file or directory)
this whiteout tends to hide indeed appears in a merged view; this is
implemented with the help of a newly introduced inode->drop flag

-------------------------
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
