      Use Makefile to replace install.sh · a2b48109
      Dave Reisner authored 
      

If we're going to use a Makefile for minilogd, we might as well use it
for everything. This has some moving pieces:

* fix minilogd rule: minilogd.o is a target dep not a build rule
* rename adjtime.cron => adjtime
* fixup PKGBUILD to account for changes

      remount root very early · 5fcb5afe
      Tom Gundersen authored 
      

This remounts root read-only as early as possible.

In FS#23845 we saw an example of what might happen if we boot with
root mounted rw and something manages to opens a file read-write
on root before we remount read-only.

      create /run/lock · eda191cf
      Tom Gundersen authored 
      

This allows /var/run and /var/lock to be symlinked to /run and
/run/lock, respectively. This would be the final step in fixing
FS#18157.

With /run/lock created early in boot it would be possible for tools
like mdadm and lvm2 to use this directory for their locking, and
maybe avoid the --sysinit parameter. This would have to be implemented
in the respective packages though.

Finally, /run/lock is created 1777 just like /var/lock is now.
For the future, it might make sense to follow systemd's lead and make
it 0755, and then create a subdir /run/lock/lockdev owned by root:lock
with permissions 0755. This would improve security and fend agains DoS
attacks, but we would have to check carefully what packages are affected.

      bootlogd: log messages to console during early boot · a5bdefd4
      Tom Gundersen authored 
      

This saves all the output during boot to /var/log/boot, which makes
debugging boot problems much simpler.

The logfile contains all the control (color) characters from boot, so
some post processing is in order before the log can be read in a nice
format (e.g. less should be able to show this nicely in raw mode).

Start bootlogd as soon as the required /dev/pts is mounted.
When boot is finished (either at the end of rc.multi or rc.single)
create the required lof file (/var/log/boot) if it does not exist. This
causes bootlogd to flush the log to disk.
Finally, send SIGTERM to bootlogd and clean up after it.

      /dev: mount /dev/pts and /dev/shm during early boot · 09c27ea2
      Tom Gundersen authored 
      

This has two purposes:

1) it allows boot services like bootlogd (that needs /dev/pts) to be
started very early in boot, and
2) by setting the standard options in rc.sysinit rather than in fstab we
have control over them and can easily integrate them with other packages
and make adjustments to fix bugs. This brings /dev/{pts,shm} into line
with how we handle /dev, /proc, /sys and /run.

With this patch /dev/{pts,shm} can (and probably should) be removed from
the default fstab file, and fstab should only contain entries for the
mountpoints the user has specified during install, like /boot, /home and
/var. It will now be possible to boot a working system with an empty fstab.

If /dev/{pts,shm} is in fstab the mountoptions there will take precedenc
over the standard ones.

      umount tmpfs on shutdown if devtmpfs is used · 9ce42645
      Gerardo Exequiel Pozzi authored 
      

This fixes FS#19783.

[tomegun:
some adjustments:
 - always umount ramfs as we never mount /dev as ramfs; and
 - don't umount /dev/pts as it might still be useful.]
