Twelve login terminals, root only, console fixes, a faster build, a Niveus splash, and X back on evdev
- tty1-tty12 all run login; the image has only root. /dev/tty7..12 could not be written (cdev.c knew minors 10-16 only), which sent their jobs into a restart storm that took the supervisor down; fixed, and stat reports them as Linux's tty7..12. - Erasing text at a prompt did nothing: erase_one sent a bare backspace, which only moves; it and the echo path now send back-blank-back through vt_feed. - A white cursor block was left at the end of every line of a verbose boot: a line feed at the bottom scrolls the pixels, cursor included, and the cursor was erased after the scroll. It comes off first now. A blank cell is also marked dirty, which it was not. - ldlsd died with a general protection fault on real hardware in its variadic log function: Linux module code calls with an 8-byte-aligned stack and an unset %al, and the prologue's movaps faults. LDLS guest code is built with -mstackrealign. - make iso took over a minute for any change, because staging r8169 rewrote the same files and every mtime moved; it now replaces files only if their contents differ (about 10 s). - The loader's splash is redrawn in the boot manager's style, and the boot manager shows its cursor whenever a pointer device exists. - xf86-input-libinput is out of the image again: with it Xorg took both keyboard and pointer from libinput and, on the user's laptop, neither worked.

* The track is wider than the mark and sits beneath it: a mark with a recessed

* track and one line of type, centred, on the same graphite the boot manager

|

* at 4K. S() is defined further down with the rest of the Niveus code, so the

* scale is applied through SC directly.
