>Why can't the book just silently change user id instead ? I use sudo. It is installed on the liveCD so in chapter 4 when I am setting up a lfs ID, I add: lfs ALL=(ALL) NOPASSWD: ALL to the exiting /etc/suders file on the live CD. Then where ever the lfs ID needs root access, I use the sudo command: sudo make install The NOPASSWD allows sudo to execute without waiting for a password. >I could alternatively do a 'su -c ./lfs-continue - lfs', essentially >passing control further via another script, but then again, i also >have variables that i need the 'lfs' user shell inherit, which I >create on my own, for different purposes. Things like timeout values, >etc... (not part of LFS, although the $LFS variable would be nice to >have exported). The sudo command is running under the lfs ID, so any variables set are valid. For places where creating a text file I use the command: sudo su -c 'cat > /etc/somefile << "EOF" Write text here And here EOF' ------------------------------ -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
