Implementation of hostname?

[ghost]

Minor feature, but:

[kalmari@localhost ~]$ sudo hostname yes
hostname: sethostname: Function not implemented
[kalmari@localhost ~]$

While not exactly what you're asking for, currently proot kompat extension supports overriding uname:

$ proot -k '\sysname\nodename\release\version\machine\domainname\-1\' hostname
nodename

(See kompat extension source for details)

You might want to set some of these values to match host system so prooted programs don't get confused by dummy uname results.

You might want to set some of these values to match host system so prooted programs don't get confused by dummy uname results.

That would be:

proot -k "\\$(uname -s)\\your-hostname\\$(uname -r)\\$(uname -v)\\$(uname -m)\\localdomain\\-1\\" uname -a

Change your-hostname to whatever you want.
