[Bug 48734] Re: Home permissions too open

Just two things that are broken with DIR_MODE=0750

(Which are still perfectly supported with the proof-of-concept
lock-down plus improved-usability script from last the post.
Independently from the additional group directories that it
introduces.)

[Bug 48734] Re: Home permissions too open

2021-01-18 Thread ceg
--- Avoiding the caveat of "this does not work"? ---

You may just not have thought yet of this solution that can be
implemented with little adjustment:

( Privacy by default? YES, even with improved usability! )


Here is a trial script:
https://salsa.debian.org/freedombox-team/freedombox/-/snippets/518


The privacy by default solution goes along these lines:

* Simply let $HOME point to /home//public_html
* /home//incoming

* /home/group/users/

* /home/group/admin/private
* /home/group/admin/incoming


These kind of different problems just need to be seen and solved together.

[Bug 1166086] [NEW] raid assembly can break into divergent parts with conflicting changes

2013-04-08 Thread ceg
Public bug reported:

Consider a laptop with a raid setup that consists of one internal disk
and a second external disk that resides in the laptops docking station.

Undocking the laptop during operation, causes the raid to switch into
degraded operation and the laptop is turned off afterwards.

Back in the office, the laptop gets mounted in the dock and is switched
on. The hardware setup is such that the disk in the docking station is
found first.

Mdadm --incremental sets up the raid device with the external disk (the
internal disk is refused by --incremental or may have been ejected).
Because the raid does not come up completely, the raid device is then
started in degraded mode with only the external disk.

We now have two divergent parts of the same raid device. The machine
runns with the old disk state as of the undocking of the laptop. All
changes made during the undocked state have been saved to the internal
disks, but they are not used now. New changes will only be written to
the external disk.

Suggested Fix:
Store the state of the event counter at the time of the degradation for each 
missing device in the superblocks on the remaining member devices.
--incremental should continue to (re)add a device automatically (only) if the 
event count shows the state of the new member device that is to be (re)added is 
equal or older than at the time the device failed.

When the incrementally assembled raid device is already running in the
(auto) read only state from an device that had failed earlier, attempt
to switch to the newer state of the added device, if that device
correctly describes the failed state of the older device (older device
event counter is equal or older than at the time it failed). Otherwise,
abort and print an error message that the devices contain conflicting
changes.

[Bug 320638] Re: hot-add/remove in mixed (IDE/SATA/USB/SD-card/...) RAIDs with device mapper on top = data corruption (bio too big device md0 (248 240))

2013-04-07 Thread ceg
** Description changed:

  Problem: md changes max_sector setting of an already running and busy md
  device, when a (hotplugable) device is added or removed. However, the
  device mapper and filesystem layer on top of the raid can not (always?)
  cope with that.
  
  Observations:
  * bio too big device mdX (248  240) messages in the syslog
  * read/write errors (some dropped silently, no noticable errors reported 
during operation, until things like dhcpclient looses its IP etc.)
  
  Expected:
  Adding and removing members to running raids (hotplugging) should not change 
the raid device characteristics. If the new member supports only smaller 
max_sector values, buffer and split the data steam, until the raid device can 
be set up from a clean state with a more appropriate max_sector value. To avoid 
buffering and splitting in the future, md could save the smallest max_sector 
value of the known members in the superblock, and use that when setting up the 
raid even if that member is not present.
  
- Note: This is reproducible in much more common scenarios as the original 
reporter had (e.g. --add a USB (3.0 these days) drive to an already running 
SATA raid1 and grow the number of devices).
+ Note: This is reproducible in much more common scenarios as the original
+ reporter had (e.g. --add a USB (3.0 these days) drive to an already
+ running SATA raid1 and grow the number of devices).
+ 
+ Fix:
+ Upsteam has no formal bug tracking, but a mailing list. The response was that 
finally this needs to be fixed [outside of mdadm] by cleaning up the bio path 
so that big bios are split by the device that needs the split, not be the fs 
sending the bio.
+ 
+ However, in the meantime mdadm needs to saveguard against the date
+ corruption:
+ 
+   [The mdadm] fix is to reject the added device [if] its limits are
+   too low.
+  
+  Good Idea to avoid the data corruption. MD could save the
+  max_sectors default limit for arrays. If the array is modified and the new 
+  limit gets smaller, postpone the sync until the next assembe/restart.
+  
+  And of course print a message if postponing, that explains when --force 
would be save.
+  What ever that would be: no block device abstraction layer (device mapper, 
lvm, luks,...) 
+  between an unmounted? ext, fat?, ...? filesystem and md?
+ 
+ As upsteam does not do public bug tracking, the status and rememberence
+ of this need remains unsure though.

[Bug 1099401] [NEW] samba maps guest users to reserved user nobody

2013-01-14 Thread ceg
Public bug reported:

The reserved system user nobody should never be the owner of files.
This ensures that an access granted with the least privileged nobody
user will never be able to access or even corrupt files on the system.
The nobody user may not even be suited for granting public read
access, if it is intended to just run unprivileged local deamons.

Samba however creates files as the nobody user when samba guests are
allowed to create files (e.g. a public share).

Expected:
Samba gets configured to use an appropriate user id for guests that are able to 
create files. This may be a samba specific user, e.g. guest user = smbguest 
to show the origin of the file, together with guest group = users (to which 
all local users should belong, bug #253103). The latter enables all system 
users to access/modify/delete the files of smbguest also directly on the 
filesystem (without going through samba shares that may have been enabled only 
temporarily).

[Bug 320638] Re: hot-add/remove in mixed (IDE/SATA/USB/SD-card/...) RAIDs with device mapper on top = data corruption (bio too big device md0 (248 240))

2013-01-06 Thread ceg
** Description changed:

- Note: Bug is also present when hot-plugging USB, Firewire etc. devices.
+ Problem: md changes max_sector setting of an already running and busy md
+ device, when a (hotplugable) device is added or removed. However, the a
+ device mapper and filesystem layer on top of the raid can not (always?)
+ cope with that.
  
- Also reproducable in much more common usage as originally reported (e.g. 
--add a USB (3.0 these days) drive to an already running SATA raid1 and grow 
the number of devices).
+ Observations:
+ * bio too big device mdX (248  240) messages in the syslog
+ * read/write errors (some dropped silently, no noticable errors reported 
during operation, until things like dhcpclient looses its IP etc.)
+ 
+ Expected:
+ Adding and removing members to running raids (hotplugging) does not change 
the raid device characteristics. If the new member supports only smaller 
max_sector values, buffer and split the data steam, until the raid device can 
be set up from a clean state with a more appropriate max_sector value. To avoid 
buffering and splitting in the future, md could save the smallest max_sector 
value of the known members in the superblock, and use that when setting up the 
raid even if that member is not present.
+ 
+ 
+ Note: This is reproducible in much more common scenarios as the original 
reporter had (e.g. --add a USB (3.0 these days) drive to an already running 
SATA raid1 and grow the number of devices).

[Bug 320638] Re: hot-add/remove in mixed (HDD/USB/SD-card/...) RAIDs - data corruption (bio too big device md0 (248 200))

2013-01-05 Thread ceg
This is a very severe data corrupting bug.

Thus, even if the the md devs can not fix the bio abstraction or
whatever would be necessary to support mixed interface setups, the md
module should definitely have a safeguard and make sure to return a
failure on hot add/remove under these circumstances, instead of letting
this bug eat it's user's data.

[Bug 1088532] Re: pluging in a missing raid member does not (re)add it to array

2012-12-11 Thread ceg
** Description changed:

  12.04.1 regression (worked before, maybe without the mentioned safety
  check, but it worked)
  
  (re-add refers to speeding up the sync using a bitmap)
  
  The --incremental (udev) call refuses to (re)add a temporarily
  diconnected member back to an already restarted (active) raid. (Even
  thought the event count clearly shows its state is equal or older than
  at the time the array was started (run) degraded.)
  
- And manually:
+ This seems to have come by an attempt to fix bug #557429, without 
considering the discussion bejond comment 68
+ https://bugs.launchpad.net/mdadm/+bug/557429/comments/68
+ 
+ 
+ And when attempting to do it manually:
  
  # mdadm /dev/md2 --re-add /dev/sda6
  mdadm: --re-add for /dev/sda6 to /dev/md2 is not possible
+ (missing info: bacause the array has no write intent bitmap)
  
  # mdadm /dev/md2 --add /dev/sda6
  mdadm: /dev/sda6 reports being an active member for /dev/md2, but a --re-add 
fails.
  mdadm: not performing --add as that would convert /dev/sda6 in to a spare.
  mdadm: To make this a spare, use mdadm --zero-superblock /dev/sda6 first.
  
+ 
  This is not how things are supposed to work in times of hotpluging.
  
  A warning/question if the device that is to be added contains newer data
  than at its time of failure is appropriate, but otherwise, get the job
  of adding that device back to its raid done!
+ 
+ 
+ To avoid regression:
+ Let --incremental (re)add members to running array again. Not doing so does 
not guard against running from alternating parts of an array anyway (if they 
come up in random order).
+ 
+ True fix:
+ Store the state of the event counter at the time of degradation in the 
superblock.
+ --incremental should continue to (re)add a device if the event count shows 
its state is equal or older than at the time the array degraded.

[Bug 1088884] [NEW] no option to force --incremental (re)add to active array

2012-12-11 Thread ceg
Public bug reported:

The --incremental call (as also done by udev rules) refuses to (re)add a
temporarily disconnected members back to an already restarted (active)
raid array.

# mdadm --incremental /dev/sdb1
mdadm: not adding /dev/sdb1 to active array (without --run) /dev/md/0

# mdadm --incremental --run /dev/sdb1
mdadm: failed to add /dev/sdb1 to /dev/md/0: Invalid argument.

Even though this refusal may in the future only happen for true
conflicts (Bug #1088532), there is still an option missing to --force
the addition anyway.

Using --force with --incremental (where mdadm will still apply sanity
checks to not add it to a completely wrong array etc.) seems much less
dangerous than forcing the user to have to --zero-superblock around in
the system.

[Bug 872220] Re: Fails to boot when there's problems with softraid

2012-12-10 Thread ceg
This is completely unbelievable. Somebody not competent enough broke the
debian raid setup for ubuntu years ago, and the issues has still not
been resolved?

Man, fix up ubuntu mdadm to issue proper notifications (bug #535417).
Get rid of that bogus boot_degraded question (bug #539597), and finally
implement a reliable raid.

@simon: good job!  Maybe the notes about the required dependencies in
https://wiki.ubuntu.com/ReliableRaid are of interst to you.

What a mistake to assume improvements in ubuntu raid and retry. Instead,
use a debian installation.

[Bug 778520] Re: install on degraded raid1 does not boot, drops to initramfs shell

2012-12-10 Thread ceg
Vak, if you need more recent versions, look for a howto to set up a
debian (desktop) box with testing or sid.

These releases contain recent software with continious updates, while
still being conservative on the finishing of features, and not just
dumping them on users and forgetting about them.

After all, ubuntu copies and releases a debian version from before it is
stable, but seems to stop adding updates after releasing that
premature version.

[Bug 1088464] [NEW] missing --incremental on array that is part of another array (nested)

2012-12-10 Thread ceg
Public bug reported:

http://www.spinics.net/lists/raid/msg40832.html

 when booting, the system dumps
 into initramfs shell with the raid array in an inactive state.

There are two problems here.

Firstly, the fact that the array doesn't assemble completely should not cause
the boot to fail.  A degraded raid1 is perfectly sufficient for booting.

What is happening is that the initrd is relying on udev to assemble the array
by passing each new device to mdadm --incremental $DEVNAME.
This will assemble the array as soon as all devices are present, but not
before.   If a device failed before shutdown that will be recorded in the
metadata and mdadm --incremental will not wait for it.  If it disappears
during reboot, mdadm will still expect it.

To deal with this issue, the initrd should run
  mdadm --incremental --scan --run

  [better: only degrade the required raid, not all !!! ]


which means look for all arrays that are being incrementally assembled, and
start them.
This should be called after running udevadm settle and before mounting the
root filesystem.

However fixing this won't fix your problem [with a nested array], it
will just change it.

The udev rules files which is calling mdadm --incremental does so
on /dev/sdb1 /dev/sdc1 and /dev/sde1, but apparently not on /dev/md0.

If at the initrd shell prompt you run
  mdadm -I /dev/md0

it should finish assembling md1 for you.  For some reason udev isn't doing
that.

Have a look in /lib/udev/rules.d or /etc/udev/rules.d for a file that runs
mdadm --incremental or mdadm -I and see how it works.
Maybe post it.

BTW what distro are you using?

[Bug 1088532] [NEW] pluging in a missing raid member does not (re)add it to array

2012-12-10 Thread ceg
Public bug reported:

12.04.1 regression (worked before, maybe without the mentioned safety
check, but it worked)

(re-add refers to speeding up the sync using a bitmap)

The --incremental (udev) call refuses to (re)add a temporarily
diconnected member back to an already restarted (active) raid. (Even
thought the event count clearly shows its state is equal or older than
at the time the array was started (run) degraded.)

And manually:

# mdadm /dev/md2 --re-add /dev/sda6
mdadm: --re-add for /dev/sda6 to /dev/md2 is not possible

# mdadm /dev/md2 --add /dev/sda6
mdadm: /dev/sda6 reports being an active member for /dev/md2, but a --re-add 
fails.
mdadm: not performing --add as that would convert /dev/sda6 in to a spare.
mdadm: To make this a spare, use mdadm --zero-superblock /dev/sda6 first.

This is not how things are supposed to work in times of hotpluging.

A warning/question if the device that is to be added contains newer data
than at its time of failure is appropriate, but otherwise, get the job
of adding that device back to its raid done!

2012-12-09 Thread ceg
Forgot to mention: conifirmed the failure to create lage enough raid
partition when trying to extend a raid 1 with another 333MiB sized
parttion (gui shows 349 MB). Nevertheless, it worked with a 18.62GiB
(20GB) raid.

Seems like messing up with with MB and MiB (MiB being the only sane unit
as this is the default alignment anyway.)

[Bug 985882] Re: units shown are not equal to the units asked for creation

2012-12-09 Thread ceg
The workarout to see the MiB size in copy/resize dialog does not work
with unknown partitions (raids containing luks).

** Description changed:

  Try to recreate or clone the OS partition on another harddrive of a
  different size as the original.
  
  GParted shows only an impresize size of the existing partition such as
  32.63GB, whereas to create the new partition the exact size in MiB is
  required.
  
  Hidden in the Properties, gparted does tell the number of sectors in the
  old partition, but that can't be directly used to create the new
  partition either. (V 0.7.0)
  
  Use case is not to copy but create two disks with same partiton sizes
  (only some of them raid partition clones).
  
  --
  
  Suggested fix:
  
- * Add the size in MiB to the detailed properties, since this is the
- standard allign unit anyway.
+ * Also show the (full length) size in MiB in the detailed properties
+ window, since this is the standard allign unit anyway.

[Bug 882255] Re: No administrative actions possible (password refused) after enabling passwordless login

2012-11-17 Thread ceg
** Description changed:

  If I choose not to have a password for my operating account, every
  operation fails if it needs root access. Reproducible even on a newly
  set up machine. See: http://ubuntuforums.org/showthread.php?t=1862543
  
  Release: 11.10
+ 
+ Cause: The password is cleared (which prevents authentification for
+ security reasons). However, the user only needs to be added to the
+ nopasswordlogin group, to enable passwordless login with gdm (and other
+ DMs that ship with a corresponding pam configuration).
  
  Steps to reproduce:
  1. Install Ubuntu 11.10 as normal. During installation, when you are asked to 
choose a password, enter one, since the installation can not continue if you do 
not do so.
  2. Boot the newly installed system and log in as usual.
  3. Choose System Settings from the launcher on the left and open User 
Accounts.
  4. In the User Accounts window, click on Unlock at the top right of the 
dialog. Enter your user password when prompted.
  5. Click on the four dots next to the Password label to change your 
password.
  6. Select Log in without a password from the dropdown box. Close the window.
  7. Try to perform an action requiring administrative privileges. For example, 
try running sudo apt-get update from a terminal.
  
  Expected behavior:
  sudo should require the user's password and accept it, or proceed without 
requiring any password altogether.
  
  Actual behavior:
  sudo requires the user's password and does not accept it (since it is set to 
an empty string in /etc/shadow).
  
  Further notes:
  After disabling the password request at login, the /etc/shadow file related 
to the test user account I created looked like this:
  test::15283:0:9:7:::
  This shows that the password hash is made completely empty; that conflicts 
with the policies listed in /etc/sudoers, which require a password to be given 
in order to perform
  administrative actions.
  
  Workaround:
  -If you can not perform administrative actions but can still login without a 
password, open a terminal and type passwd. This command should prompt you for 
a new password and change it without any problems.
  -If you can not login, you can reset your password by booting into recovery 
mode and changing it there. Follow the instructions at 
http://psychocats.net/ubuntu/resetpassword.
  
  You may also choose to use a password for your account and to enable
  autologin at the same time. This choice will enable you to benefit the
  advantage of not entering a password at boot time with the security of
  Ubuntu requiring your password when attempting to perform privileged
  actions. Of course, this helps when you are the only desktop user or the
  primary one.

[Bug 251646] Re: {upstream} missing command to start *single* arrays in auto-read mode (like --incremental)

2012-09-04 Thread ceg
I don't think so.

My guess is that if initramfs calls

mdadm --incremental --run

it would run all arrays and not just the single array (mdX) that contains the 
root filesystem.
Degrading not yet fully available non-root arrays is bad, as it may nullify the 
redundancy and take hours to get the arrays resynced again.

diverge, and if the non-rootfs devices become accessible later they need
to resync.

[Bug 251646] Re: {upstream} missing command to start *single* arrays in auto-read mode (like --incremental)

2012-05-21 Thread ceg
** Description changed:

  Binary package hint: mdadm
  
+ Proposed command: mdadm --incremental --run /dev/mdX
  
- Initramfs has to start (selected) md devices in degraded mode. (The ones that 
contain the rootfs and swap/resume partition, if they didn't start after some 
time of udev hotplugging.)
+ Initramfs must be able to start (selected) md devices in degraded mode
+ (only the ones that contain the rootfs and swap/resume partition), if
+ they didn't start after some time of udev hotplugging. Starting all
+ arrays, that are not yet complete at that early stage, degraded is not
+ acceptable.
  
- It seems to be preferable to use --incremental not only in the udev
- rules but also in the boot scripts, because is said to support auto-
- read mode for smoth inclusion of members that appear later on.
+ Initramfs could use the old non-incremental commands,
  
- But the boot script should only start selected arrays, i.e. the one
- containing the rootfs not all incomplete ones.
+ ( i.e. mdadm --run /dev/mdX is preferable to mdadm --assemble --scan
+ to start only selected array degraded)
  
- So where mdadm --run /dev/mdX is preferable to mdadm --assemble
- --scan (only start selected array degraded),
+ but the old commands break the support for auto-read mode set up and
+ smooth inclusion of members that appear later on.
  
- something like: mdadm --incremental --run /dev/mdX or to start all
- arrays in auto-read mode by default might be preferable to both.
+ 
+ Alternatively to a new --incremental option, make the old commands compatible 
and also start degraded arrays in auto-read mode and incrementally extendable 
by default.

[Bug 251164] Re: boot impossible due to missing initramfs failure hook / event driven initramfs

2012-05-15 Thread ceg
Looking at the timouts suggested in Comment #15, I think they may actually be 
realizable with modular scripts. A base rootdelay script, and separate mdadm 
and cryptsetup sripts (that get called by their udev rules) can halt/extend the 
regular rootdelay (exported variable? named pipe?), if waiting for user input 
or a new level of raid degrading timeout. (As pipes block, reading from pipes 
may do good for event based processing.)

Phillip, your idea of handling udev events by modular event handlers (that may 
again trigger udev events, if I interpret you correctly) may also be what 
appears in part of the OpenRC discussion.

I don't know if daily wake events can be programmed in the hardware real
time clock.

Yes, a small +wakup again checkbox or similar collapsible UI to enter
a date would be sufficient I guess. But if it the UI could remember the
last setting used this might already also allow daily (next day)
wakeups.

For facility wide power saving schedules I think debian has a shutdown-

[Bug 251164] Re: boot impossible due to missing initramfs failure hook / event driven initramfs

2012-05-14 Thread ceg
I believe the initramfs only sets up the rootfs, other partitions
(/home) are set up afterwards. If I remeber correct cryptsetup is called
by udev rules. In any case, that is the way it has to be, event driven,
to catch on upon (/home) devices appearing without polling loops and
sleep delays.

When I looked, I think bootwait, mdadm and cryptsetup where all looping
and sleeping in initramfs independently in whatever course they get
called. Therefore I suggested the watchdog timers I mentioned above and
in the wiki.

[Bug 251164] Re: boot impossible due to missing initramfs failure hook / event driven initramfs

2012-05-13 Thread ceg
The udev rules don't need to prompt, the cryptsetup that gets called
will prompt. Actually, these things work quite well in the normal
system. It seems preferable to me to adjust/improve the regular tools to
be usable in initramfs as well, rather then trying to script up and
maintain! another thing inherently limited.

Failure hooks for example will be called in a specific order (not
necessarily matching the setup), if you are looping this should time out
with a message, then if the user plugs in the missing disk it won't come
up automatically (and if it does possibly only with a large delay as all
unrelated loops need to time out first), etc. Thus, its better to go
event driven, and then why not favor a proven tool.

Reasonable timeouts (see above and https://wiki.ubuntu.com/ReliableRaid)
are another reason to go event driven, they should not be several
waiting loops stacked up and possibly blocking each other.

2012-05-13 Thread ceg
 Since udev already provides an event driven framework in 
the initramfs, why add another one?

Hmm, if you would like to realize event driven init scripts, I believe
you may be able to rework the scripts from doing linear pre...post
things to just call a watchdog script that mostly sleeps and checks how
things are going on. And then have separate task scripts that get only
called by udev events, or the watchdog.

[Bug 531240] Re: silently breaking raid: root raid_members opened as luks

2012-05-12 Thread ceg
Thank you for testing, Phillip!

Cryptsetup support should be on the CD.  But it only seemed to run in the first 
boot up stage of the rescue CD and used to try to open the raid members there, 
even before you set up the raids with the debian installer.
Good that it does not do that any more.

I thus consent that the bug can not be reproduced with new installs
anymore. It could be though, that this is only due to a newer mdadm
superblock version being used in newer installs. (I think the 0.9
version is at the end of the partion.)

Nevertheless, as you can see mdadm, lvm, and cryptsetup will need an
improved event driven (udev) setup in the the rootfs and initramfs (both
used also in the installer system) to setup the devices no matter how
they are stacked up. Bug #251164

If you still have the vm setup, you could just try to boot the text
installer media again, enter the rescue mode and see how it wants to
mount the existing raid disks (not degraded, both present) in the vm.
That's where it used to always happen. Oherwise, only occasionally
during normal reboots.

 When trying to boot with one disk missing, the system would not boot

Right, after way too many release cycles with the unmaintained mdadm
modifications in ubuntu, I moved upstream.

** Description changed:

  The desktop environments would help saving energy, if their shutdown

  Linux provides a simple way to schedule a restart event that is

- rtcwake -m on -s seconds-util-start-event

any switching into another power state (mode -m stays on).
  This allows that all power state switching is still contolled by whatever  
power management (userspace) tools are installed, which may often be more 
stable than the pure kernel/rtcwake method, especially on resume.
  
  To test it, just schedule a wake event like above as root, then do a

2012-05-08 Thread ceg
When I had the problem I finally had to turn to CLI-parted to get the
proper numbers. Nothing a graphical tool user may like to do, but I
could work around the problem that way.

Fortunately, I was using the MiB allignment on all newer disks, so they
should have ended up to have the same size as I defined exact MiB, too.

It just feels really wrong if the graphical partitioning tool you are
using asks for information in a unit that it can not supply (without
going into unrelated modes). It would have been no problem if the info
is in the detailed properties. Thus if you could add it there, that
would be great.

[Bug 987664] Re: allow to set restart/resume time

2012-04-30 Thread ceg
** Description changed:

+ The desktop environments would help saving energy, if their shutdown
+ dialogs could by default provide the option (button/checkbox) to
+ schedule a restart.
+ 
  Linux provides a simple way to schedule a restart event that is
  particularly usefull in conjuction with initiating or scheduling a
  shutdown or suspend.
  
  rtcwake -m on -s seconds-util-start-event
  
  Howerever, just as the shutdown command it requires root privileges.
+ Thus the need for a similar consolekit support.
  
  The particular command given in the example above avoids that rtcwake does 
any switching into another power state (mode -m stays on).
- This allows that the power state fully handled by the regular installed power 
managment (userspace) tools, which is often more stable than the pure 
kernel/rtcwake, especially on resume.
+ This allows that all power state switching is still contolled by whatever  
power management (userspace) tools are installed, which may often be more 
stable than the pure kernel/rtcwake method, especially on resume.
  
- To test it, just schedule a wake event, then do a regular
- shutdown/suspend. Later, the real time clock will trigger the scheduled
- power up event and the machine comes back up.
+ To test it, just schedule a wake event like above as root, then do a
+ regular shutdown/suspend. Wait, and watch how the real time clock
+ triggers the scheduled power up event and the machine comes back up.

[Bug 884011] Re: regression: lost ability to show continuous status with tray/appindicator icon

2012-04-29 Thread ceg
Hi Peter-Alexander,
you're right, and I agree it still is a regression looking at the 
--notification function alone. As far as I understand the reason for the change 
was the decision for an updated semantic. Notification now only means a bubble 
message, and is different from a status icon or window. Going with this might 
be more precise. But changing this without giving apps the chance to adopt and 
use a --trayicon option if they actually do need a continuous status indication 
one is really bad.

** Description changed:

  The change in the zenity --notification behavior completely removed
  the functionality to display an unobtrusive, always visible tray icon
- from zenity. Instead, that functionality should have been moved into a
+ from zenity.
+ 
+ For clarity, the tray icon functionality should be made available with a
  proper zenity --trayicon feature.
+ 
+ For backwards compatibility, the --notification option would have to

  Ubuntu 11.10
  zenity 3.2.0-0ubuntu1
  
  In a script I use following line:
  exec 3 (zenity --notification --window-icon=icon.svg --listen 
--text=some text)
  so I can change the tray icon based on what the script does.
  
  What I expect to happen:
  zenity --notification should show an icon in the tray or appindicator.
  
  What happens instead:
  A zenity --warning style dialog window pops up.

In any case, it would be good if you could post the issue to the upstram
bugtracker.

Hi jacopoL, you set this to invalid, because you don't know about start
events?
