- 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.

Job manifests for schinit, SchOS process 1.
Every *.job file in this directory is loaded at boot. Format is sectioned
key = value; # starts a comment, keys are case-insensitive.
Label a reverse-DNS name, as launchd uses. Identity, not a path.
Program the binary to execute
Args argv, space separated. argv[0] is conventionally the
basename, so `Args = sh` for `/bin/sh`.
RunAtLoad start it when schinit loads
KeepAlive restart it when it exits
Disabled load it but do not start it
ThrottleInterval seconds between respawns (default 1)
StandardIn \
StandardOut > paths to open as fd 0, 1, 2
StandardError /
[Socket <name>]
Path a unix socket schinit will hold on the job's behalf and
start the job on first connect
A KeepAlive job that exits with status 78 (sysexits.h's EX_CONFIG) is not
restarted, and schinit says which job stopped and that it stopped on purpose.
This is for a program that has looked at the machine and found nothing here it
can run against -- a driver whose device is absent, say -- which would otherwise
report the same thing every ThrottleInterval for the rest of the uptime. A job
that was killed or crashed carries a signal in its status, never matches, and
comes back exactly as KeepAlive promises.
Socket sections are parsed but not yet acted on -- that is milestone 2, and
demand launching is the whole reason this is shaped after launchd rather than
sysvinit. The key exists now so manifests do not have to change later.
Unknown keys and unknown sections are ignored rather than fatal: a manifest
written for a newer schinit must not stop this one booting the machine.
