As of deets 0.1, you can now also populate Cosmo template variables through Lua code. For example:

/tmp/silly.lua:

require("utils-grep")

local intel = grep_program_output("VGA.*Intel","lspci")

file.file({"/tmp/garbage"}, {
    ensure = "present",
    owner = "root",
    group = "root",
    mode = "755",
    source = file.cosmotemplate("/tmp/silly.cosmo", intel)
})

/tmp/silly.cosmo:

# On $systeminfo|hostname, we might have used the following information
# to populate this config file.
#
# We did not.

$map{$v|1}[[# $it]]

Then run sudo luau --rectify /tmp/silly.lua and your /tmp/garbage should be equally useless whether or not you have an Intel video card.

I am holding a device running MeeGo 1.2 Harmattan 1.2011.22-6PRRM680, courtesy of the good folks at Nokia.

If you have debootstrapped the internal microSD card, the vendor-supplied U-Boot config should serve you adequately.

To boot off of a USB stick, however, interrupt the boot sequence (if you don't have a JTAG/serial board at this point, go buy one immediately), and enter the following commands:

setenv x_bootcmd_kernel fatload usb 1:1 0x6400000 uImage
setenv x_bootargs_root root=/dev/sdc2 rootdelay=10
saveenv
reset

If you just want to testboot once, and don't want to make it permanent, omit the saveenv. If you do want to make it permanent, consider removing the superfluous pings from the bootcmd, but be careful to escape semicolons and dollar signs instead of zealously copying and pasting.

If you haven't bothered putting a FAT partition with uImage on the USB stick, omit the setenv x_bootcmd_kernel line.

Once you've booted Debian, you may wish to natively-debootstrap or copy your new partition to /dev/sda2 (which is what Linux will call the ext3 partition of your microSD card).

To then return to fully booting off of microSD so you can repurpose the USB stick,

setenv x_bootcmd_kernel fatload usb 0:1 0x6400000 uImage
setenv x_bootargs_root root=/dev/sda2 rootdelay=10
saveenv
reset

Enjoy.

Finally (2010.09~rc1-2) I am running Debian's U-Boot on the Sheevaplug, and booting with this env:

bootcmd=run bootcmd_mmc; bootm 0x300000 0x0800000
bootargs=console=ttyS0,115200 root=/dev/mmcblk0p2
bootcmd_mmc=mmc init; mmc init; ext2load mmc 0 0x0800000 /uInitrd; ext2load mmc 0 0x300000 /uImage

Having to run mmc init twice is annoying, but it beats dealing with whichever fork I had on it last.

I am betting that Luakit will be more usable than Uzbl within a week. I am also betting that I will hear chirping about Luakit not integrating with the Monkeysphere, and though I agree that this is a problem, it seems to be difficult to solve.

To do it correctly, one would need hooks or callbacks in WebKitGTK+, which, in turn, would need support in LibSoup, which would probably then need support in GnuTLS.

Since apparently this will take years of bickering to accomplish, perhaps some sort of hack is called for. I suppose one could, for each HTTPS URL visited, make an OOB connection, download the certificate, and then run it through Monkeysphere validation, before then letting WebKitGTK+ make another connection and download (hopefully the same) certificate a second time.

This strikes me as ugly and problematic. Ideas?
