## Re: some feedback on refracta2usb/installer

Thanks thwak, those links helped.

Code:
  `# comment them all in locale.gen
  sed -i '/^[a-z][a-z]_/s/^/# /' /CENSORED/locale.gen
  # find the current active locale and uncomment it
  CURRENT_LOCALE=$(cat /CENSORED/default/locale | grep -o "[a-z].*")
  sed -i "0,/# $CURRENT_LOCALE/s/# $CURRENT_LOCALE/$CURRENT_LOCALE/" /CENSORED/locale.gen`

Voila! The current active one only is now checked when dpkg-reconfigure locales is run. Works also in installer preinst script.
BTW a sid image rebuilt with the line for "user" removed from sudoers has sudo working with "components=sudo" (config=sudo in old live-config) on cmdline.

That second part doesn't work for me. CURRENT_LOCALE gets part of the comment at the head of locale.gen along with the default locale. I get the following sed error:

Code:
  `sed: -e expression #1, char 34: unterminated `s' command`

The following does work for me.

Code:
  `CURRENT_LOCALE=$(grep -v ^\# CENSORED/default/locale | cut -d= -f2)
  sed -i "s/# $CURRENT_LOCALE/$CURRENT_LOCALE/" /CENSORED/locale.gen
  `

That code to get $CURRENT_LOCALE likely didn't work for you because /***/default/locale looks like this:

Code:
  `# File generated by update-locale
  #LANG=en_US.UTF-8`

It does in official refracta7 (BTW no set default can cause other problems) and maybe in a debootstrap.

Code:
  `cat /***/default/locale |grep -o "[a-z].*"
  ile generated by update-locale
  en_US.UTF-8`

It works if you boot using "config-locales locales=whatever" because that file gets overwritten by live-config with no header. Therefore your way is more robust (the header, if exists, is excluded) Thanks for clarifying that.
However.. there could be duplicate entries in locale.gen, official refracta7 has. Maybe the duplicates came from package upgrades. My last sed line was done to get the first matching line only. I don't know what happens if two duplicate lines are uncommented.
This tangent really belongs in "experimental"..

I can tell you that the duplicate entries don't come from changing the default to a different locale and then changing it back. I went from us to gb and back to us, and only the current one was in default/locales.
Um, I thought there were problems with no default locale set and other problems when a default locale was set. Don't remember particulars, though. I've been running for awhile with no default and haven't had a problem. (Also pretty sure I was the one who had the problem when no default was set, but that was on a previous installation.)

Don't remember what happened with no default locale, might have been something in newer xfce. It will pop up again somewhere.
Saw this today in a live custom sid:

Code:
  `# dpkg-divert --list
  # (SNIP)
  diversion of /usr/sbin/update-initramfs to /usr/sbin/update-initramfs.orig.initramfs-tools by live-tools
  diversion of /usr/share/man/man8/update-initramfs.8.gz to /usr/share/man/man8/update-initramfs.orig.initramfs-tools.8.gz by live-tools
  diversion of /usr/share/man/man1/uptime.1.gz to /usr/share/man/man1/uptime.orig.procps.1.gz by live-tools
  diversion of /usr/bin/uptime to /usr/bin/uptime.orig.procps by live-tools`

The installer should probably cleanly reverse those dpkg-diverts. They are still listed in my (wheezy) installed system.
EDIT
I noticed also, in one of my live-builds made from debootstrap, there was no /***/shadow. I haven't tried refractainstaller on that yet but would expect a problem. It is there in official Debian xfce image. To run "shadowconfig on" however does no harm if is already is.

It was wicd that wanted a default locale. I guess that's no longer a problem.
wicd-problem-t236.html
Guess I'll also need to do something about this bit of code, in case someone is using the installer on a system that does not have live-tools installed.

Code:
  `# Run update-initramfs to include dm-mod if using encryption
  if [[ $encrypt_os = yes ]] || [[ $encrypt_home = yes ]] ; then
  chroot /target /usr/sbin/update-initramfs.orig.initramfs-tools -u >> "$error_log"
  fi
  `

My mistake.. seems live-tools does the diversions in the installed system then installs its own version (which automatically detects if it's a live running system or not) Therefore the diversions should be there. I'm still not clear what happens to (live) update-initramfs if live-tools is not installed.

I'm not clear on any of this. Here's what you get if live-tools is not installed. This is the same on an installation and in a snapshot iso (in sid).

Code:
  `locate update-initramfs
  (slash)etc/initramfs-tools/update-initramfs.conf
  /usr/sbin/update-initramfs
  /usr/share/man/man5/update-initramfs.conf.5.gz
  /usr/share/man/man8/update-initramfs.8.gz
  /var/lib/dpkg/triggers/update-initramfs`

And this is with live-tools installed (in refracta 7). Here, /usr/sbin/update-initramfs is s symlink to /bin/live-update-initramfs.

Code:
  `/bin/live-update-initramfs
  (slash)etc/initramfs-tools/update-initramfs.conf
  /usr/sbin/update-initramfs
  /usr/sbin/update-initramfs.orig.initramfs-tools
  /usr/share/man/ca/man8/live-update-initramfs.8.gz
  /usr/share/man/de/man8/live-update-initramfs.8.gz
  /usr/share/man/es/man8/live-update-initramfs.8.gz
  /usr/share/man/fr/man8/live-update-initramfs.8.gz
  /usr/share/man/man5/update-initramfs.conf.5.gz
  /usr/share/man/man8/live-update-initramfs.8.gz
  /usr/share/man/man8/update-initramfs.8.gz
  /usr/share/man/man8/update-initramfs.orig.initramfs-tools.8.gz
  /var/lib/dpkg/triggers/update-initramfs
  `

Here's some code that's been in the installer since Dean's version(s). I don't think it's needed anymore. If it is, I need to understand how it relates to what live-tools does with update-initramfs. I'm going to comment out these lines.

Code:
  `# copy the real update-initramfs back in place
  if [[ -f /target/usr/sbin/update-initramfs.distrib ]] ; then
  cp /target/usr/sbin/update-initramfs.distrib /target/usr/sbin/update-initramfs
  fi
  if [[ -f /target/usr/sbin/update-initramfs.debian ]] ; then
  cp /target/usr/sbin/update-initramfs.debian /target/usr/sbin/update-initramfs
  fi`

And here's the replacement for the section I posted a couple of messages up. This should work whether or not live-tools is installed, but I haven't tested it yet.

Code:
  `# Run update-initramfs to include dm-mod if using encryption
  if [[ $encrypt_os = yes ]] || [[ $encrypt_home = yes ]] ; then
  if [[ -f /usr/sbin/update-initramfs.orig.initramfs-tools ]] ; then
  chroot /target /usr/sbin/update-initramfs.orig.initramfs-tools -u >> "$error_log"
  else
  chroot /target /usr/sbin/update-initramfs -u >> "$error_log"
  fi
  fi`

It reverses what live-config (/lib/live/config/)105-initramfs-tools in pre-wheezy does. I think it's deprecated now and live-tools does the job (stops update-initramfs on an RO filesystem) Little of this is documented to that level, we have to work it out for ourselves by reading those scripts and experimenting.
You probably should have live-tools installed (although I don't think it's a dependency of live-boot) It is in the official Debian xfce image.
