Hello there! I updated my USB installer instructions for the latest CentOS7.3, as likely as not they will work just fine for SL7.3. https://daqshare.triumf.ca/~olchansk/linux/CentOS7/AAA-README-USBBOOT.txt https://daqshare.triumf.ca/~olchansk/linux/CentOS7/ Documented is how to create a bootable USB disk (16GB or larger USB flash) with a kickstart installer for el7.3. The main reason for creating yet another installer is to disable the idiotic requirement of "you must create a fake user account to finish the installation" (courtesy of gnome-initial-setup). (This is done in the kickstart file ks.cfg via "-firstboot" and "-gnome-initial-setup"). The main bonus is to have a kickstart installer where I can trivially specify the timezone, etc (the stock CentOS/SL installer images do not have any simply way to add a custom kickstart file) (My SL6 USB installer has/had a wide selection of memtest programs, I hope to add them back to the el7 installer eventually). (It should be possible to add custom packages to the installer, but I have not figured it out yet. I know people on this list have been wondering about such a feature. For now, you can throw any custom packages into the installer root directory and install them by hand from the kickstart scripts). -- Konstantin Olchanski Data Acquisition Systems: The Bytes Must Flow!
