Package: e2fsprogs Version: 1.46.2-2 Severity: normal File: /sbin/mke2fs X-Debbugs-Cc: j...@joshtriplett.org
mke2fs with -E offset=N does not seem to take the offset into account when checking the target to see if it seems to already contain something. For instance: /tmp$ truncate -s 1G disk.img /tmp$ echo '8,+,L' | sfdisk --lock --no-reread --no-tell-kernel disk.img Disk disk.img: 1 GiB, 1073741824 bytes, 2097152 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes >>> Created a new DOS disklabel with disk identifier 0x729c5118. disk.img1: Created a new partition 1 of type 'Linux' and of size 1024 MiB. disk.img2: Done. New situation: Disklabel type: dos Disk identifier: 0x729c5118 Device Boot Start End Sectors Size Id Type disk.img1 8 2097151 2097144 1024M 83 Linux The partition table has been altered. /tmp$ mkfs.ext4 -E offset=4096 disk.img mke2fs 1.46.2 (28-Feb-2021) Found a dos partition table in disk.img Proceed anyway? (y,N) I deeply appreciate that mke2fs checks for existing data before overwriting it, and I'd prefer to not just pass -F here. I think the "plausible" checks should take the offset into account. -- System Information: Debian Release: 11.0 APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'unstable'), (1, 'experimental-debug'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: arm64 Kernel: Linux 5.12.8 (SMP w/4 CPU threads) Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages e2fsprogs depends on: ii libblkid1 2.36.1-7 ii libc6 2.31-12 ii libcom-err2 1.46.2-2 ii libext2fs2 1.46.2-2 ii libss2 1.46.2-2 ii libuuid1 2.36.1-7 ii logsave 1.46.2-2 Versions of packages e2fsprogs recommends: pn e2fsprogs-l10n <none> Versions of packages e2fsprogs suggests: pn e2fsck-static <none> pn fuse2fs <none> pn gpart <none> ii parted 3.4-1 -- no debconf information
