Hello syslinux, Merry Christmas! These patches will make extlinux work with umounted ext2/3/4 filesystem, for example: $ extlinux -i /dev/sdXN or $ extlinux -i file_block Also it can work with something like: $ extlinux /dev/sdXN --reset-adv or $ extlinux file_block --reset-adv We don't use a new option (I planed to use "-d" but it is already in use), it will check whether the

Turns out Japanese trains are good for coding! In supermin we have a bunch of code to create the libguestfs appliance. It creates it directly using libext2fs (part of e2fsprogs). We can use the same technique to create ext2 virtual disks in nbdkit, which is what this new plugin does. Why a new plugin instead of modifying the floppy plugin? See the 4/4 commit message for an explanation. The

Another interesting thing you can do with this plugin: https://rwmj.wordpress.com/2019/02/19/nbdkit-linuxdisk-plugin/ v2: - Fix inconsistent tab/space. - All 3 plugins now contain a block of text pointing to the other 2 plugins. - TMDIR -> TMPDIR - Unlink the temporary file and other cleanups along error paths. - fclose -> pclose, and check the return value for errors. -

Hello, Happy New Year! These patches make syslinux/linux support ext2/3/4, and it doesn't require the root privilege, I'd like to add a separate e2fs/syslinux, if that is more appropriate, it should be easy to do that. I put these patches on github so that you can easily get them in case you'd like to test them. (The repo's name is sys_tmp, which avoids confusing others, I will

Hi, to ease debugging issues with appliances (e.g. when used in libguestfs), using --include-packagelist will add a file containing the list of all the packages used.

Hello, Recently, I am coding a program about read and write control. And there are some questions confusing me. 1. In info libext2fs: Function: errcode_t ext2fs_get_blocks (ext2_filsys FS, ext2_ino_t INO, blk_t *BLOCKS) Returns an array of blocks corresponding to the direct, indirect, doubly indirect, and triply indirect blocks as stored in the inode structure. So I wrote some codes like following: blk_t target_blks[EXT_N_BLOCKS]; retval = ext2fs_get_blocks(fs, ino, target_blks); printf(&quot...

Hi, the two patches improve the way memory is handled in supermin, by cleanly exiting on memory allocation failures, and free'ing memory when not needed (to keep working and not run out of memory).
