Rickard Nilsson 8fe8ab7097 switch-to-configuration.pl: Fix parsing of comments in fstab, hash-tokens inside strings are not comments. 2013-01-25 15:54:45 +01:00
Rickard Nilsson e32e501435 activation: Don't use double quotes in boot loader warning message, it messes up perl system call 2013-01-25 15:47:38 +01:00
Eelco Dolstra 4d983d4955 Rename ‘system.build.systemd’ to ‘systemd.package’ 
This makes it cheaper to test a new systemd and is more consistent
with other modules.

Eelco Dolstra 827e3dadc8 Don't special-case systemd-journald.service and systemd-user-sessions.service 2013-01-08 17:00:45 +01:00
Eelco Dolstra 1541311f06 switch-to-configuration: Stop some target units to ensure proper dependency ordering 
This is currently only done for network-interfaces.target, but
it should propably be done for most targets.
 2013-01-07 16:06:45 +01:00
Eelco Dolstra 96ba0ca283 For some units, use "systemctl restart" rather than "systemctl stop/start" 
During a configuration switch, changed units are stopped in the old
configuration, then started in the new configuration (i.e. after
running the activation script and running "systemctl daemon-reload").
This ensures that services are stopped using the ExecStop/ExecStopPost
commands from the old configuration.

However, for some services it's undesirable to stop them; in
particular dhcpcd, which deconfigures its network interfaces when it
stops.  This is dangerous when doing remote upgrades - usually things
go right (especially because the switch script ignores SIGHUP), but
not always (see 9aa69885f0).  Likewise,
sshd should be kept running for as long as possible to prevent a
lock-out if the switch fails.

So the new option ‘stopIfChanged = false’ causes "systemctl restart"
to be used instead of "systemctl stop" followed by "systemctl start".
This is only proper for services that don't have stop commands.  (And
it might not handle dependencies properly in some cases, but I'm not
sure.)

Eelco Dolstra 9aa69885f0 Don't do readlink() on every mount point when remounting /dev etc. 
Doing so causes the activation script to hang if (say) an NFS mount
point is unreachable.

Eelco Dolstra 8adc1ee92e switch-to-configuration: Stop sockets corresponding to services 
If a service has a corresponding socket unit, then stop the socket
before stopping the service.  This prevents it from being restarted
behind our backs.  Also, don't restart the service; it will be
restarted on demand via the socket.

Eelco Dolstra b52117c34d Treat init-script as a boot loader 2012-07-25 11:30:16 -04:00
Eelco Dolstra b15e1fbb08 Boot loader refactoring 
- Renamed system.build.menuBuilder to system.build.installBootLoader.

- ‘install-grub.pl’ (formerly grub-menu-builder.pl) now generates the
  GRUB menu *and* installs GRUB (if necessary).

- ‘switch-to-configuration.sh’ has no boot loader specific knowledge
  anymore.  It just calls installBootLoader.

Eelco Dolstra f0c82f4543 Pass the ‘--recheck’ flag to grub-install 2012-07-24 19:22:19 -04:00
Eelco Dolstra f07f221f0e Replace grub-menu-builder with a much faster version 
The old GRUB menu builder script is quite slow, typically taking
several seconds.  This is a real annoyance since it's run every time
you switch to a new configuration.  Therefore this patch replaces the
Bash script with a much faster Perl script.  In a VirtualBox test, the
execution time went from 2.7s to 0.1s.  The Perl version is also more
correct because it uses XML to get the GRUB configuration (through
builtins.toXML), so there are no shell escaping issues.

The new script currently lacks support for subconfigurations defined
through "nesting.children".
