[9fans] create /home

[9fans] create /home

[Rudolf Sykora]

Hello,

I'd like to create a directory /home and then bind it to /usr.
(This is because I want some paths from linux that start with /home
were valid paths in my plan 9, too.)

However, I can't create a directory in my / --- when writing 'mkdir
/home' I get the message

mkdir: can't create /home: '/home' mounted directory forbids creation

I remember I was once solving this problem and if I am not wrong, it
was related to the fact that '/' is an union directory and there was
no directory bound to '/' with creation allowed. But somehow I now
don't know where and what I should change, so that I can create a
directory in '/'... I tried to change
the information in /lib/namespace, which in my case starts with

mount -aC #s/boot /root $rootspec
bind -a $rootdir /

to either 'mount -acC' ... or 'bind -ac', but the former seems to not
help and the latter results in no ability to boot afterwards...
(this was just a try, I don't really know what's really going on...)

Can anybody help?
Thanks!
Ruda

Just this results in the same/similar:

mkdir: can't create /root/home: '/root/home' mounted directory forbids creation

Thanks

or you could just...

; aux/stub -d /home
; bind /usr /home

...

option a: remount with -c option.  requires permission to
scribble on /.
	mount -c /srv/boot /n/boot
	mkdir /n/boot/home

option b: use fossil / ken fs console
	filsys main
	create home uid gid 755d
	create home uid gid 755 d 	# kenfs

That's not enough if the linux filesystem is given

I bumbed into permission problems...

I finally did this:

con -l /srv/fscons
at the prompt wrote fsys main
wrote create home ruda ruda 755
ctrl-\
q

but I can't see any /home ...
I didn't write 755d because it didn't like that...
