I'm working on writing /etc/magic entries for ZFS. Below is the start that I've made. It uses XDR for the header which has pascal strings with a 4 byte big-endian length. I thought that should be "pstring/L" but the following pstring types are the ones that worked. Also running "file -s -k /dev/sd?" doesn't work, is the -k option expected to work on a device node? 0x4010 belong 0x20 -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
