Subject: [PATCH v8 0/8] erofs-utils: mkfs: introduce rebuild mode
Date: Wed, 13 Sep 2023 20:02:55 +0800 [thread overview]
Message-ID: <20230913120304.15741-1-jefflexu@linux.alibaba.com> (raw)
v8:
- patch 7: fix the missing call for erofs_mkfs_dump_blobs() in rebuild
mode by also calling erofs_mkfs_dump_blobs() when sbi->extra_devices
is not zero; otherwise the content of the on-disk device slot is all 0
- patch 8: strip overlay.opaque xattr when --ovlfs-strip=1; update the
commit message accordingly

-------------------------
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 layer0.erofs ... layerN.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 layer0.erofs ... layerN.erofs
