Fstab NFS mounts fail because they start before the network is available in Debian Buster (10)

I recently upgraded Debian Stretch (9) to Debian Buster (10). Since then, my NFS deployments by fstab fail because they are started before the network is available, as noted in the boot log.

I tried with _netdev in the entry nfs but this has nothing. Of course, I can include the NFS file system sudo mount -a, Is there a way around this problem?

History – Why are tripod mounts not metric?

[BetrachtenSiedieseNeuformulierung:Waswäre[Considerthisre-framing:Whatwouldbe[BetrachtenSiedieseNeuformulierung:Waswäre[Considerthisre-framing:Whatwouldbewon with a metric tripod?]

The core of why metric tripod mounts are unusual is a combination of:

  • Legacy standards
  • Immediately available parts / tools
  • Lack of a good reason for a change

At the beginning of the 20th century, a variety of tooling standards were set before metric tools became popular. This led to a long-lasting snowball effect in some industries, such as camera equipment.

With much of the gear on the market already using the 3/8 standard and 1/4/20 standard, the introduction of a new metric thread gear became far more impractical.

Little to nothing new in the vicinity of the metric thread used meant that there was little economic reason to make a change.

  • Who wants to buy a tripod that needs an adapter plate for its cameras?
  • Who wants to buy a camera that does not fit on the existing tripod?

Screws for the camera assembly had a much lower barrier to entry into the metric – it does not matter which standard you choose or whether each screw in the camera body has been machined to a different standard. If no one is expected to replace the screw itself or screw it into something else outside the camera, it really does not matter what you used.

Server Message Block – SMB mounts well if kbr5 is used, but no explicit credentials

At my company, we tested SMB to replace NFS servers.
When mounting Windows server shares everything works as expected. ie:

mount.cifs //windows.domain.com/share/mnt/windows/o credentials = / home / ttest / .smb
# OR
mount.cifs //windows.domain.com/share/mnt/windows/ -o sec = krb5, uid = $ UID, gid = team, cruid = $ UID

For this test we have a Centos 7.6 server with Samba 4.8. Windows machines can fine mount the share, and Centos clients can mount it with the sec = kbr5 option.

The matter

I can not figure out why I can not mount this share with explicit permissions! ie:

mount.cifs //linux.domain.com/share/mnt/share/ -o sec = krb5, uid = $ UID, gid = team, cruid = $ UID
mount.cifs //linux.domain.com/share / mnt / share / -o credentials = / home / ttest / .smb

dnd 5e – Can mounts be attacked instead of their mount, and which characters in the battleship receive occasional attacks?

This is a question that I have raised with my group, and although I have made a decision, I hope for a more authoritative answer (sage advice?).

The rules for reported battles do not seem to specify exactly how targeting works attack action, I summarized the mechanics of PHB 198 below, with the last rule shown in italics, as it is the subject of this question:

A mount is:

  • A willing creature
  • At least one size larger
  • has an adequate anatomy to drive

Mounted and dismantled:

  • If you are within 5 feet of a mount, you will need half your speed of movement for assembly or disassembly
  • If the mount is moved against the will or you are prone, you will be exposed to the mount at 5 feet (5 feet).
  • If the mount becomes prone, it will be removed within 5 feet of the mount. You also become vulnerable if you do not spend your reaction.

Actions and Movement:

  • A controlled mount must be a trained or domesticated creature that matches your initiative while riding. You can move the mount at its speed, and only add a dash, deactivation, or dodge when it is effective. Controlled mounts can move and work in the round in which they are mounted.
  • Independent mounts must be intelligent creatures, acting independently, maintaining their initiative order, movement, and full agency (presumably actions, bonus actions, reactions, etc.).
  • If a mount triggers an opportunity attack while riding, the attacker may target the mount or rider,

The target rules of a Attack of opportunity is specified, but can be attack action are you also targeting the mount or the rider when the mount is aiming?

By default, Mounted Combatant Feat suggests that by default, attacks target the mount by default, but it remains unclear whether the driver is allowed to hit the target on each mount:

  • "You can Makes an attack aimed at your mount to target you "

As a final related question which mounted fights of an independent mount and rider can use their reaction to make an opportunity attack against an enemy leaving the fields lying next to the mount?

I assume, but it can be wrong, that a controlled mount loses its bonus actions and reactions and thus can not execute an opportunity attack.

dnd 5e – Can mounts dominate armor?

As far as I can tell, there are hardly any rules on this subject. All we have is:

PHB, chapter 5, page 144: (generally armor)

Armor knowledge. Anyone can put on armor or put on a shield
to an arm Only those who know the armor know how to wear it
it effectively, however. Your class teaches you with specific knowledge
Types of armor. If you wear armor with which you have no abilities, you are
have a drawback with every skill check, save, or attack roll
this includes strength or skill and you can not cast spells.

Conclusion: Anyone who wears armor must be competent or face the consequences.

PHB, chapter 5, page 155: (on cash as equipment, price)

Barding Barding is an armor that covers the head, neck and neck
Chest and body. Any type of armor displayed on the armor table
This chapter can be purchased as cash. The cost is four times
Equivalent armor for humanoids, and it weighs twice as much.

In summary, you can armor an animal and the price is four times that of a normal armor.

PHB, Appendix D, page 310: (Variant rule especially for Warhorse)

Variant: Warhorse armor
An armored Warhorse has an armor class based on the type of Bards worn
(For more information about Bards, see Chapter 5). His armor class includes the
if necessary the modifier "Dexterity" of the horse.

In summary: A war horse can wear armor. Warhorse, unlike riding horse. Since this is a deviant rule, it implies that without the deviating rule, all beasts (not just warhorses and war dogs, war elephants, etc., as I suppose) can bear bards.

But do you need knowledge? In accordance with the general rule for armor strength listed above; Yes, How would an animal acquire such ability? Besides, we are not told what the difference between a riding horse and a fighting horse is and whether / how the first one can become the latter.

However, if the RAW is missing, we just keep rolling. The spirit of the game was always "make up as you go". So I would suggest the following: A non trained warrior does not control the armor. A war-trained mount is. I believe that this is relatively consistent with the above rules.

We also have to set some rules for training a warbeast. Do you say rigorous training for a month or two in the hands of a specialist?

Yes, and that's what I mentioned: a lawyer could argue that bards and armor are two different things. I would say that it is the same with different names, depending on the wearer.

Lens – Can mounts be replaced on Vivitar 75-205mm lenses?

The only way to be sure if the brackets can be changed is to try. You may even find that the "damaged" lens can be used as well as possible.

If the lenses are the same model with different mounts It is likely that they have a large part of the same construction so that the brackets can be changed. However, different brackets often have mechanical connections that function differently, which can make changing these brackets difficult.

When you try to change the brackets, The aperture ring must probably be changed as well, Make sure that you do not lose any parts, eg. B. the ball bearing, through which the opening engages.

If you can find service manualsYou can tell if it's worth the effort.

RAID mounts stop – ask Ubuntu

I have a recently built (a few weeks ago) Z370 HD3P PC with two RAID-1 arrays connected via the Intel RST hardware RAID. One is NTFS and the other is Ext4. I noticed this morning that the Ext 4 RAID can no longer be mounted, but the NTFS system runs well with 4.15.043. When I boot to 4.15.042 everything works fine again and both arrays are mounted.
I installed some Ubuntu updates yesterday. Is it possible that anything has been damaged? I have done several tests and am sure that the file system on the array has no hardware issues or corruption that is not being deployed now. The error I get is the wrong default Fs type, bad option, bad superblock message (udisks-error-quark, 0).
Does anyone have any suggestions as to what happened?

Is there a semi-automatic way to clean up / dev / loop mounts?

My system seems to generate more / dev / loop mounts for certain updates.
So far it looks like this:
/ dev / loop0 128M 128M 0 100% / pressure / Yakyak / 28

Is there a tool that can detect which ones are no longer used and release them? Not that this causes a problem, I prefer less clutter with mount points.
