Hello,
I want to let a freshly installed Plan 9 box use NTP but can't get it
to work.
I used the explanation under "SETTING UP CORRECT TIMEZONE" from
http://plan9.bell-labs.com/wiki/plan9/installation_instructions/ but
noticed some things:
- User adm cannot edit /rc/bin/termrc because it is owned by user sys
and group sys and user adm isn't a member of the sys group. I could
make user adm a member of the sys group but this is probably not the
way to go.
- User glenda is a member of the sys group and can edit
/rc/bin/termrc, so I changed the TIMESYNCARGS variable, saved, quit
sam and checked with p /rc/bin/termrc. However, after rebooting, the
change is lost (in outer space?). I also noticed that the copy of
the termrc file I made before making the change, was gone.
I checked the manpages for boot, booting, root, namespace... but
didn't really find the exact reason. I think it has to do with the
fact that the directory I see as user glenda, is a union directory
which only allows me to change the file in the current namespace. If
that's the case, it's probably not the intention that I change it as
user glenda either.
What am I missing here?
Kind regards,

assuming you are running the file server on this very machine, did you
run fshalt before rebooting?

No I hadn't... I thought that fshalt was only necessary when you want
to turn off the box and that a reboot would first sync the filesystem.
I just read the "SHUT DOWN" section from the installation instructions
again. The sentence "Then turn off the computer or type Ctl-Alt-Del or
"^t ^t r" to reboot" indeed implies that you have to run fshalt before
rebooting (in case the system runs a fileserver).
Thanks for your help.
Kind regards,
