Have you tried a restore? A non-differential smap snapshot should be fine, but differential snapshots would make a restore difficult to impossible.

A zfssend and zfsrestore with a differential snapshot would be more traditional. If one put mbuffer in the middle, it would even be fast.

I disagree with the premise that Android is Linux "fixed". Sudo is a bridge for privilege compartmentalization. There is root on Android.

And for many of those points there is a solution, but not one many want to use. SELinux is poorly document and has a bad reputation, but does work. File systems can be mounted as to not execute anything on them.

Good topic idea though, I just disagree with the specific examples.

Looks like you have your answer, but there are a crazy number of possible issues.

The biggest cause is misreading the performance specs.

A partial list of other options:
Mechanical drives store data in rings. Outer rings have higher speeds than inner due to constant angular velocity.
Seeks cost a lot of throuput on mechanical drives.
Oversubscribed drive cables.
HBA issues.
PCIe data path conflicts
Slow RAM
RAM full or busy
Extra cpy within RAM
NUMA path issues (of drives are connected to different NUMA nodes. Not an issue on desktops.)
CPU too busy
Transfer software doing extra things
File system doing extra.
RAID doing extra.
NIC on a different NUMA node than HBA (can be good or bad).
NIC sharing the data path in a conflicting way.

There are others. Start with checking theoretical performance from data sheets.

Also, details matter, and I don't have enough of them to guess.

“Jewish by association”

Sounds pretty not good. Cultural appropriation with a side of self centeredness.

Also, pretty antisemitic.

Are there better words to clearly label this?

A man was sexually assaulted in jail

This kind of shit has to stop. The jailers must help held accountable. I understand this is difficult due to bad laws, but the laws need to change.

Sorry, I don't mean the police.

Article is from a year ago. Government tends to be ahead of the curve. As an uninformed guess, they have been using it in high value situations for 4+ years.

(Dear FBI, the above is a guess based on public information. I don't know shit.)

Thank you. That was very clear. I look forward to seeing the results of the developments.

Sure, but not one of those is a reason to use it.

Please give me one example of how sublinks is better than lemmy currently for use.

(I don't understand why new software instead of improving lemmy.)

Kinda related: what if I install something like Debian/Ubuntu on it? Can I still use the NAS hardware in the same way?

This question confuses me. Debian and Ubuntu can be setup to be NASes.

NAS is a description of a mid-level function that various software provide a part of.

Various file systems and volume managers can provide snapshots and rollbacks. To aid your research LVM, ZFS, and many others support snapshots.

There are various ways to then expose the formatted space to the network. To aid research NFS, SMB, and iSCSI are options.

Anyway, I hope this is helpful to someone.
