nerdctl rename broken (with --network host, none)

[apostasie]

Description

nerdctl run --network host -d --name test1 debian sleep Inf
nerdctl rename test1 test2

FATA[0000] open /home/dmp.linux/.local/share/nerdctl/1935db59/etchosts/default/bda418243819bf46ac0f8a52f88310ba6ed77e4038febda296df158f65295889/meta.json: no such file or directory

Futhermore, this will leave the system in a broken state, where the destination name is locked.

This is likely related to #2613 which I was debugging before hitting this.

No response

Debugging notes:

• with network=host, hoststore never writes the meta file (which is causing the rename to fail)
• it works with ocihooks - in applyNetworkSettings, which is called onCreateRuntime, and again onStartContainer

Likely related issues:

• add-host parameter not valid #2591
• hostname is always overwritten by container id in container when using --network=host #2694
• Parameter --add-host not working when using also --net=host #2613
• and to some extent Import /etc/hosts entries automatically #355

[apostasie]

In summary, when network=host, if we are to mimic docker behavior:

• hostname should be the host hostname (and not the container id)
• the container /etc/hosts should include entries from the host /etc/hosts UNLESS --add-host is specified
• --add-host should work

I find the exception on number 2 to be ridiculous, and would rather treat it as a bug on Docker side rather than implementing it.
