I've verified now that this works, and also verified that syslinux properly detects the sha256 and sha512 passwords. This patch updates the usage message for HDT. Based on current master, ignoring patch I sent a few minutes ago.
and trivial fix for comment in conf
Don't bother mention salt or other crypto algorithms. Also wrap the lines with comments.
We allow a password to be set in /etc/update-extlinux.conf. Instructions for generating this are in /etc/update-extlinux.conf. For reference, here is another (equivalent) way to generate the MD5 password: openssl passwd -1 -salt yy pass If one sets a password, one will presumably want to make /etc/update-extlinux.conf world-unreadable. We don't do that for you; however we do make sure when a password is present to make the /boot/extlinux.conf files we generate be world-unreadable. Of the auto-generated entries, only HDT (if this is generated) is now configured to respect the password; however, you can include "MENU PASSWD" in any entries you put in /etc/update-extlinux.d/. For example, I configure my BIOS to only boot from the internal drive, but I have an entry in /etc/update-extlinux.d that permits chain-booting from a USB key, and I have this entry configured to also require the password. (The BIOS is also passworded, so that these settings can't be changed willy-nilly.) Conflicts: main/syslinux/update-extlinux.conf
HDT provides a curses-like interface to display lots of hardware info about your machine at bootloader time. We don't install /boot/hdt.c32, but if it's present (it can be copied from /usr/share/syslinux/hdt.c32), we add a menu entry for it---in preference to, rather than in addition to, memtest, since HDT has a menu entry which invokes memtest. Using HDT to its full capacity requires finding or generating modules.pcimap and pci.ids files for your machine, and installing them in /boot. We might want to document this, which I don't here (but the online docs for HDT do). These aren't required to use other functionality of HDT; and it's pretty useful already without those.
We don't install /boot/reboot.c32, but if it's present (it can be copied from /usr/share/syslinux/reboot.c32), we add a menu entry for it---just like with memtest. Add a comment to /etc/update-extlinux.conf stating this. It'd already be possible to get a reboot entry using the /etc/update-extlinux.d/ folder, but this patch provides a more intelligent framework with nicer layout. The syslinux sourceball also provides a shutdown module, but I couldn't get this to work and looking at the sources reveals it to be for machines with APM enabled. Not sure how many machines that applies to anymore.
