Re: [foxboro] Can anyone explain how /etc/fox/user_apps.log and / usr/fox/ia16/etc/user_apps.log are "conected"?

WPs "see" their logical hosts file system as part of their own through
the
use of micro-RFS.

To support WP20/30 and newer stations from the same host, there are two 
"I/A
Series file systems" on the 51-Series machines:

1) /usr/fox/ia16 is the file system seen by WP20/30s.
2) /usr/fox is the file system seen by WP51s.

The two are not "linked" there are mounted onto each other using the 
'mount'
command and the file system type of 'local file system (lofs)'. You can 
see
this in the /etc/vfstab file.

As you can see, /etc/fox is mount to /usr/fox/ia16/etc. Because of this
anything in /etc/fox is also found in /usr/fox/ia16/etc.


Similar, but not identical effects, can be accomplished with the 'ln' or

'ln
-s' commands.


Hope this helps.

OK, Im stumped. This morning while trying to figure out why the root
filesystem on an AW was at 100%, I tracked it down to
/etc/fox/user_apps.log. Later in discussing with a co-wokere he said
that
file lived in /usr/fox/ia16/etc. Turns out we were both correct. And
somehow the 2 files are conected. I can't find a symboilc link for this,
and it can't be a hard link, as / and /usr are different disk partions.

Even stranger, they do have th smae inode number. 

What am I overloking here?
