how to pin files to /tmp
Hi all,
Am currently working on editing a startup script that need me to copy a certain file from cdrom to /tmp (its a live cd am working on)and mount if from there to certain place..
Now i know that nothing can be stored in /tmp permanently ,however mechanism to load the file to /tmp on every boot is possible...
So i would like to know how it could be done.
Here is what i have tried (this editing that ive done is on the script that is necessary to boot properly, so there is no other script that i can code this line into ,in the pretext of making it work)
cp /.cdrom/<file> /tmp/
i included this into the script and try to boot ,but a regular cp command doesnt seem to be working...
However there are a few file that are already present on /tmp, if i can know how they were loaded ,i could use the same method..
please help
Thanks

ZDIFF(1) BSD General Commands Manual ZDIFF(1)
NAME
zcmp, zdiff -- compare compressed files
SYNOPSIS
zcmp [options] file [file2]
zdiff [options] file [file2]
DESCRIPTION
zcmp and zdiff are filters that invoke cmp(1) or diff(1) respectively to compare compressed files. Any options that are specified are passed
to cmp(1) or diff(1).
If only file1 is specified, it is compared against a file with the same name, but with the extension removed. When both file1 or file2 are
specified, either file may be compressed.
Extensions handled by gzip(1):
o z, Z,
o gz,
o taz,
o tgz.
Extensions handled by bzip2(1):
o bz,
o bz2,
o tbz,
o tbz2.
Extensions handled by xz(1):
o lzma,
o xz,
o tlz,
o txz.
ENVIRONMENT
TMPDIR Directory in which to place temporary files. If unset, /tmp is used.
FILES
/tmp/zcmp.XXXXXXXXXX Temporary file for zcmp.
/tmp/zdiff.XXXXXXXXXX Temporary file for zdiff.
SEE ALSO
bzip2(1), cmp(1), diff(1), gzip(1), xz(1)
CAVEATS
zcmp and zdiff rely solely on the file extension to determine what is, or is not, a compressed file. Consequently, the following are not
supported as arguments:
- directories
- device special files
- filenames indicating the standard input (``-'')
