Hi all.

Could I change the kernel version tag manually? say, I have a kernel
which is 7.0-CUREENT, but for some reasons I wanna it be something like
6.1-RELEASE, while the kernel itself does't change from 7.0-CURRENT to
6.1-RELEASE. All I want is the change of tag. For example, if this works,
then when I type "uname -a" in console, I would get "6.1-RELEASE ..."
instead of "7.0-CURRENT ...".

I guess some config files in src/sys/ could take care of this. But I
cannot find it out. Anybody knows how to get this job done?

Any ideas are really appreciated. :-)

BTW: I am not in this list. So if you reply, please CC a copy to me.
Thanks.


Changing the represented release name is not a generally wise idea. You
may also want to modify sys/sys/param.h, consult the FreeBSD Porters'
Handbook for more details.

If you just want to cheat uname(1) and/or sysctl(8), perhaps renaming
them to _uname and _sysctl and use some sort of _uname $@ | sed -e
s/`_uname -r`/6.1-RELEASE/g trick will do. This also applies to the
rc.d motd script, which uses uname(1) to determine the current FreeBSD
version. This trick is less intrusive, but have no effect if your
application read the version themselves, e.g. the build process of
python, etc.



Thanks for this enlightment. Very helpful :-)



ENVIRONMENT
An environment variable composed of the string UNAME_ followed by any
flag to the uname utility (except for -a) will allow the corresponding
data to be set to the contents of the environment variable.
