/1 and /2 ?

["Charles R. Anderson" <cra WPI EDU>]

What the heck are the /1 and /2 files for?

[root foo /]# ls -l /[12]
-rw-r--r--  1 root root 161 Mar 21 22:28 /1
-rw-r--r--  1 root root   0 Mar 21 22:28 /2

[root foo /]# cat 1
make: Entering directory `/etc/security/selinux/src/policy'
make: Nothing to be done for `/dev/null'.
make: Leaving directory `/etc/security/selinux/src/policy'

Looks like temp files leftover from something in the install 
process, since the timestamp is before that of install.log:

[root foo root]# ls -l install.log
-rw-r--r--  1 root root 62700 Mar 21 22:47 install.log

and this was a fresh format + everything install.
