[06:54] <twb> So I need some generic help with initramfs-tools.
[06:55] <twb> In 8.04 I placed an extra script in /usr/share/initramfs-tools/scripts/casper-bottom/13home, which adds a line to /root/etc/fstab (prior to pivot_root).
[06:55] <twb> When I do the same in 10.04, and run "update-initramfs -u" to regenerate the ramdisk, I see that 13home is being executed *at update-initramfs time*.  That is insane, and I don't understand why it's happening.
[07:11] <twb> OK, I think I worked it out
[07:12] <twb> It seems that nowadays update-initramfs calls *every script* at generate time, with a single argument "prereq".
[07:12] <twb> And all the scripts separately have a check "if $1 is prereq, exit immediately".
[11:49] <cjwatson> twb: yup.  speeds up boot quite a bit, but it did require every script to be changed.
[11:49] <cjwatson> doing the ordering at boot time with relatively few tools was slow
[11:50] <twb> Hang on; are you saying that the files in casper-bottom/* are reordered, a la insserv?
[11:50] <cjwatson> yes, initramfs-tools does that for everything - casper-bottom/* happened to be already ordered by way of numbers in the filenames, but not everything was
[11:51] <twb> I see.
[11:52] <twb> So my casper-bottom/foo scripts should emit something like "X-Start-Before: pivot_root" and "Depends: rootfs" ?
[11:53] <twb> Or: where's the best place to read documentation about this
[12:01] <cjwatson> no, it isn't *actually* insserv
[12:01] <cjwatson> you can just have them exit immediately when called with the 'prereqs' argument, and then filename order will be used
[12:02] <cjwatson> otherwise, echo your script's dependencies to stdout when called with 'prereqs', and then exit immediately
[12:02] <cjwatson> that's about as far as it goes
[12:02] <cjwatson> /usr/share/doc/initramfs-tools/examples/example_script documents it
[12:03] <cjwatson> (and _hook)
[12:11] <twb> AFAICT nothing in my system has a non-empty PREREQS="" lst
[12:11] <twb> *list
[12:22] <cjwatson> you're not running lucid then?
[12:22] <cjwatson> $ grep ^PREREQ /usr/share/initramfs-tools/scripts/init-top/console_setup
[12:22] <cjwatson> PREREQ="framebuffer"
[12:22] <cjwatson> $ grep ^PREREQ /usr/share/initramfs-tools/scripts/init-top/udev
[12:22] <cjwatson> PREREQ="all_generic_ide blacklist"
[12:22] <cjwatson> etc.
[12:23] <cjwatson> although casper doesn't use it, we use it fairly extensively in initramfs-tools itself
[12:24] <twb> I was looking at Sid
[12:25] <twb> It is still synchronous?
[12:25] <cjwatson> unstable's initramfs-tools doesn't appear to use it, though it has the facility (merged from Ubuntu)
[12:25] <cjwatson> yes, it's still synchronous
[12:25] <twb> OK, thanks

[20:46] <EtienneG> repost of a question send to #ubuntu-devel: is there any way we can force installation of a restricted driver at install time, through preseeding?  Would invoking "jockey-text -e nvidia" as a late_command be sufficient?
