...onfusing (ext from extlinux and ext from ext2/3 filesystem), for XFS code xfs_read_adv is called which is static inline int xfs_read_adv(int devfd) { const size_t adv_size = 2 * ADV_SIZE; if (xpread(devfd, syslinux_adv, adv_size, boot_image_len) != adv_size) return -1; return syslinux_validate_adv(syslinux_adv) ? 1 : 0; } boot_image_len for me is about 53 kb so it read after 53 kb after start of partition however comment on ext_read_adv state that 2kb is used. Also in ext_write_adv adv is written with a write_adv which use a file inside the filesystem so the first function looks wrong to me...

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

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
