On hppa, we have a getty on ttyB0 with the following line : b0:12345:respawn:/sbin/agetty 9600 ttyB0 vt100 This is not being commented out by livecd-functions.sh while updating inittab. This leads to two getty being started on the same tty, you end up with both the login prompt and the bash prompt. The attached trivial patch fix the problem.
Created attachment 256509 [details, diff] Patch for livecd-functions.sh.
Fixed without a revision bump in 1.0.42. CCing wolf31o2 in case he wants to take this upstream after all. :)
