I tried this from my normal user shell (zsh)
su - -m root -c 'echo $SHELL'
That is not the right shell for root, which on my box uses bash.
All the env variables : USER HOME SHELL are values for the normal user,
not the root user. But the mess is a bit deeper - even though I am using
the environment of the normal user (despite the leading - to su), I seem
to have root privileges. When I run
su - -m root -c gvim
I can actually edit the files that only root has write permission for.
So largely, the su -m approach lets gvim work with root privelelges,
although the environment seems to be all wrong.
1) Is there some way I can actually do all the above from the root user
account, using the normal user's existing X server ? I think that
happens under Linux, so in theory it should be possible under FreeBSD
too (even if merely as a hack).
2) gvim on my box has been compiled with GTK3+ support. GTK support
enables specifying a --socketid. I wonder what is that and how to get
the socket id of an existing GVIM session. Plus, could using socketid
solve the issue of running gvim from the root account directly ?
Thanks for replying.
