   It seems to me that after an hdinstall /etc/hosts always contains
   127.0.0.1 localhost slitaz tazpanel
   where slitaz is not always the real hostname.
   would it be possible to make tazinst change /etc/hosts in the end of the install process or maybe in function users_settings(), something like sed -i 's/slitaz/realhostname/' /etc/hosts ?
   thanks

   User must make changes to configuration template file before installation.

   Install with tazpanel:
   http://tazpanel:82/installer.cgi?page=install
   Hostname
   Set Hostname to: Your hostname here

   Install from console:
   tazinst new install.conf
   vi install.conf
   # Hostname
   TGT_HOSTNAME="Your hostname here"
   # tazinst install install.conf

   again, thanks for your answer.
   i did set hostname in install.cgi and it correctly transfers the value to tazinst:
   

   ...
   INSTFILE=/var/lib/tazinst.conf
   ...
   sed -i s/"^TGT_HOSTNAME=.*"/"TGT_HOSTNAME=\"$TGT_HOSTNAME\"/" $INSTFILE

   but in the ending system in the hard disk i have the correct hostname and the wrong /etc/hosts.conf .
   e.g. in my hd installed system hostname is slitvaio and i had "127.0.0.1 localhost slitaz tazpanel" in /etc/hosts , which i edited to "127.0.0.1 localhost slitvaio tazpanel".
   this is the reason why i think that tazinst sets only the hostname and doesn't care about /etc/hosts.
   not a big problem but if i have the wrong /etc/hosts and two different slitaz system in my network, e.g. slitvaio and slitaz, slitvaio trying to ping slitaz would end in slitvaio pinging itself.
   messing with slitaz's script it's a little scaring to me :-) and devs probably would fix this trivially (if it's considered to be fixed), but if devs have no time and i'm allowed i could try to fix it myself and post here results.

   tazinst : http://hg.slitaz.org/slitaz-tools/file/066dd36cc2cc/installer/tazinst
   Line 707 => echo $TGT_HOSTNAME > etc/hostname
   We can use this instead:
   sed -i s/slitaz/$TGT_HOSTNAME/ /etc/hosts /etc/hostname

   for what i can understand it should work.
   i would not use the prepending slash before every etc, original command does not use it and the presence of the command cd $TARGET_ROOT in the beginning of the function at line 691 makes me feel scared to break something.
   if you can push it i can do some test when new version will be available.
