>Release: FreeBSD 4-STABLE i386
>Organization:
Cronyx Plus LLC (RiNet ISP)
>Environment:
System: FreeBSD 4-STABLE
>Description:
When using sudo instead of su, environment is slightly different.
In particular, both $USER and $LOGNAME are set to root after sudo -s.
There is at least one annoying side effect of this: kernel build user
mentioned is always 'root'.
In this case the only reliable way to get logged-in user name is
/usr/bin/logname. Following patch utilizes it.
>How-To-Repeat:
For example, using old-way kernel compile:
sudo -s
cd /usr/src/sys/i386/conf
config GENERIC
cd ../../compile/GENERIC
make vers.c
grep compile vers.c
